Aqua Rebell Makro Basic NPK















Aqua Rebell Makro Basic NPK
Description
In a strongly lit well-planted tank or in aquariums with few fish a lack of macronutrients may occur, which in turn can lead to poor plant growth. Makro Basic NPK adds the most important macronutrients of nitrogen, phosphate and potassium to the tank. The plants can once again access plentiful resources, resulting in lush growth as an expression of gratitude.
Weekly water changes of 25 - 50 % are recommendable. The dosage can be raised or lowered depending on the requirements. If the aquarium water shows high readings of nitrate and/or phosphate from the start, this fertilizer is not suitable, though. It has been designed to prevent the accumulation of large concentrations of macronutrients. If high levels of nitrate and/or phosphate occur, the dosage should be reduced.
The basic supply of macronutrients in a tank is provided either by our NPK fertilizer, our Estimative Index fertilizer or by our single-nutrient fertilizers (Makro Basic Nitrat, Phosphat and Kalium). Our waterplant fertilizer Aqua Rebell Makro Basic NPK adds nitrogen, phosphate, potassium and magnesium and thus covers all the essential macronutrients, providing the plants with the prerequsites for lush growth. This fertilizer has been designed to prevent the accumulation of large concentrations of macronutrients, as a rule, however, the daily dosage should just cover the daily amount the waterplants use. The dosage recommendation is a very good starting point for the individual adjustment of the fertilization to the own aquarium. Especially with regard to macronutrient fertilization, a certain amount of personal effort is required when determining the appropriate dose, as the macronutrient input is additionally influenced by variables such as fish stocking and food input.
When fertilizing, however, it should generally be noted that a micronutrient fertilizer (complete iron fertilizer) is also required in addition to the NPK fertilizer.

Since I started using this fertilizer, my plants are thriving.
Of course, micronutrients should be added as well (iron fertilizer)

I had Sven Breitenbach from Aquasabi advise me on fertilization and then finally switched to this product and Micro Eisen from Aquarebell. I really have to say that after approx. 4 weeks I'm already very happy. My stem plants are not only growing up again in rich green, but are also forming side… (read more)

No matter what size aquarium - best value for money!

As described, everything went smoothly and without any problems. Would buy again

Simply a tip-top fertilizer.
Have been using the Aqua Rebell line for almost 3 years now and am completely satisfied with it

Hi,
in my opinion the fertilizer is a bit heavy on potassium.
With the fertilizer calculator the dosing can be adjusted.
Greetings from Berlin

Very happy and the plants are growing noticeably better
Great, always happy to order again

Have been using it for a while and I have to say it's a really great product and the plants show their thanks right away

Switched from Dennerle Düngesystem,S7,E15,V30 to Aqua Rebell because I could never detect nitrate and phosphate in my tank! Some plants had deficiency symptoms because of that!(nitrogen) Now I fertilize daily with the NPK and iron fertilizer, I'm very surprised how everything is growing now! It… (read more)

I've tried many fertilizers, and I really like fertilizing with this one, it's great and makes nice strong plants, very happy.

Good price with an enclosed brochure with tips and information on fertilizing.

I've tried many fertilizers, this one has achieved the best results so far.

I really like fertilizing with this one, it's great and makes nice strong plants, very happy

The fertilizer does what it's supposed to do, the plants grow fast, sturdy and look very good. Will keep using the fertilizer. Thanks to Aquasabi for the fast delivery and the great customer service.

I think the product is tip-top. Highly recommend it. My plants like it a lot. Thumbs up for NPK

Great fertilizer with excellent value for money. The dosing recommendations regarding NO3 and PO4 are absolutely spot on, so the nutrients can be set optimally. I haven't tested potassium yet, so I can't say anything about it. The plants definitely grow much healthier and deficiency symptoms… (read more)

Very happy. 1-day delivery, really great.
I'm convinced of Aqua Rebell products anyway and very happy with them.
Aquasabi has one more regular customer.

Have used it from the start, and am totally happy with it. If you forget it, boom, algae. So best never forget. Only in combination with CO2.
300l

Since the switch to Aqua Rebell NPK + Eisen, there has been a clear improvement in plant growth. Brown, discolored leaves or languishing plants are no longer to be seen. Now regular trimming is more the order of the day.

I'm very happy with this fertilizer. I also use the iron fertilizer from Aqua Rebell. I searched for a suitable fertilizer for a long time and finally found one that gives my plants exactly what they need.

Bought this fertilizer for my small aquarium. My plants are growing wonderfully and are colorful. I use it in combination with Aqua Rebell Flowgrow and it works great.

Highly recommended in combination with or alongside other Aqua Rebell products, and it's important to always observe the dosages.

Bought the fertilizer three weeks ago and so far it seems to suit all three of my tanks. So I can only pass on my recommendation. However, you really have to keep in mind that the quantities given are only a guideline. I was already able to determine that the recommended amounts are not enough for… (read more)

Super fast delivery, 1 day after ordering. Plants thrive very well with Makro Basic and CO2. Inexpensive, easy to handle, all great. Keep it up.

The fertilizer is easy to use and transparent in dosing and effect. The nutrient calculator on flwogrow.de is highly recommended for finding the desired dosage, especially when combining fertilizers.

This fertilizer system works quite well for me, so I'll stick with it. You should at least supplement this NPK Basic with the iron fertilizer from the line. My plants respond well to it and look well fed :)

The dosing instructions are great. After I had corrected the phosphate and nitrate deficiency (I'm sure one or the other micronutrient was still missing) with the NPK fertilizer, plant growth really took off after about three weeks. In parallel I'm using the iron fertilizer plus the micro… (read more)

What more is there to write. Have been using the fertilizer for years and am still completely satisfied. The delivery was well packed.

We've been fertilizing with Aqua Rebell for about four months now. On top of Makro BASIC NPK, we also use the iron fertilizer from Aqua Rebell.
Plant growth has gotten noticeably better and we have absolutely no problems with algae. We dosed both fertilizers slightly higher than stated.

A very easy-to-dose base fertilizer and, combined with Eisen Basic, an excellent fertilization system for both daily and weekly dosing.

Pretty good for beginners
Whether it's also good in the long run remains to be seen
As for dosing, don't fixate on the instructions on the bottle
Use the Flowgrow calculator or do it like I do
Start very small with 1 ml per 40 liters and measure the values every 3 days
Then you can work with it

I've been using the fertilizer for a while now and I really have to say that it works great in my scape. I combine it with the iron fertilizer from Aqua Rebell and my tank is running super stable and the plants are growing excellently.

Does what it's supposed to do. Plant growth is absolutely great. For a 30 l tank, the bottle lasts forever. We'll buy it again next time.

The plants get a very rich green. Very satisfied. Great product. The best part is the dosing pumps, you don't always have to fill a cup.

Highly recommended, and when I asked about possible pre-fertilization, support gave me a quick answer right away, always happy to order again!

I bought the small bottle to try it out. Since my plants have been growing like crazy ever since, I'll go straight for the jug in the future ;)

I tried the fertilizers from Aqua Rebell on a recommendation and I'm thrilled. Besides Makro Basic NPK, I also use Mikro Basic EISEN with great success.

I've been using the fertilizer in combination with iron fertilizer for approx. 3 months. Now the measurements have shown that potassium builds up very strongly in the tank. While phosphate is not detectable in my aquarium water with fertilization and nitrate is at 1 mg, the K value is at 20 mg. I… (read more)

I dose the NPK fertilizer from AR daily in my 60P, in combination with ADA Brighty K and AR iron fertilizer. The plants say thank you with beautiful growth.

I use Aqua Rebell Makro Basic NPK in several tanks and I'm very satisfied with it. I tried switching to individual components as a test, but I'm now back to Makro Basic NPK.

Aqua Rebell is a highly recommended NPK fertilizer for aquariums with less dense planting and standard lighting.

The NPK fertilizer combined with an iron fertilizer and CO2 makes my plants grow magnificently and show off beautiful colors, too.

Once you've found the right dosage, everything thrives splendidly. Regular water changes of at least 50% every 5-7 days are a must, though, at least in my tanks. No signs of algae at all, but rock-healthy plants with vigorous growth. As always, the ordered products were delivered very quickly and… (read more)

I've been fertilizing with it for approx. 1 year and I'm very satisfied.
The plants have strong shoots and healthy colors.
With the pump it's also easy to dose.

Good price for this Makro Basic NPK with a perfect nutrients dosing. Contains magnesium too. I add weekly in my tank.

I've been using it for 6 months together with Flowgrow and it delivers everything you'd expect from it. My plants are growing and are rock-healthy. I've tried many products and this was the best.

Good NPK fertilizer. The shrimp and fish are doing well so far and the plants are growing and are happy, too.

I use the fertilizer together with the Micro Basic iron fertilizer. Good plant growth and hardly any algae. What more could you want? :-)

Since there's already too little nitrate in my tap water, my plants grew very poorly. In tanks with few fish, phosphate is lacking as well, which I was able to compensate for perfectly with the fertilizer. Thanks to the strong growth of the plants, there is now much less algae.

The plants grow very well and my discus tolerate it well, too. Great value for money as well. And something that really needs to be said: at aquasabi you always get great advice.

Very good fertilizer with very good value for money. Fast delivery. Very large selection with good phone consulting. Can be recommended to anyone.

Because of my plants' high demand, I chose the 5 l container size this time, after having had great experiences with the 1 l bottles. Here the value for money is of course even better, and the liquid can easily be transferred into other bottles. On the back, just like on the bottles, you'll find… (read more)

The ingredients are clearly labeled, which makes dosing possible without any problems. The bottles are sturdy and the cap has a child-proof lock. With the matching accessories, dosing becomes even easier, and the price is very fair.

In the past I've tested many fertilizers (including Tropica and others) and have now arrived at the full range from Aqua Rebell. EXCELLENT! I'm currently very satisfied with the Mirko Spezial Flowgrow. In addition, I dosed N and phosphate individually and arrived at similar amounts to what's… (read more)

Great NPK fertilizer in a handy bottle. With the dosing attachment (available separately), clean and easy application. Would buy again!

Excellent quality liquid fertilizer. Started using this product about an year now and don't think changing. Plants looking great and full of colour.

A highly recommended fertilizer. Everything is still growing well, but the algae stay away. Very well suited for daily fertilization.
I've tried many fertilizers and stuck with this one! Great!

At the beginning I had my concerns about nitrate and phosphate. Now, after almost a year with Makro-Basic NPK, I can say that I have one of the best liquid fertilizers. I'm currently dosing 5 ml per 100 l of water and 1 ml of Makro-Spezial N per 50 l. In addition, there's 1 ml of Mikro-Basic EISEN… (read more)

The liquid fertilizers from AquaRebell are simply perfect. Shipping was fast and uncomplicated. I highly recommend these fertilizers. Here only the clear facts and values count, not some advertising slogan and false promises. Keep it up! Best, Tim W.

I've already tried quite a few well-known fertilizers.... But NONE comes even close to Aquarebell. After approx. 1 to 2 weeks I got such great plant growth ! I will NEVER buy another one

Hassle-free processing and very fast delivery. The product is first-class and highly recommended. Always happy to order from Aquasabi.

Clear and odorless. Unfortunately the dosing recommendation doesn't match my consumption. Product as shown in the picture. No dosing pump included as described I need 5 times the amount in my aquascape. Also, the nutrients are split up the wrong way: while I have a potassium excess, I have a… (read more)

Since I started fertilizing with aquarebell NPK and iron fertilizer, the plants have been growing incomparably well. I have a 54 l aquarium and with the dense planting, the plants are very grateful for the fertilizer.

Aqua Rebell Makro Basic NPK fertilizer is a very good fertilizer, especially within the Aqua Rebell fertilization system - highly recommend!

Every aquascaper should own it!! Very well tailored to aquascaping and very easy to handle thanks to the pump part. The bottles could be a bit nicer - the competition has realized that as an aquascaper you also like to show what you use to care for your plants... ;-)

Great product, does exactly what it's supposed to, it makes the plants grow splendidly. I've now been using it for over a year and I keep coming back to it.

Highly recommended, I've been using it forever, everything works great! Now I don't know what else to write here.

Before, I was using EasyLife Profito, had no problems, great growth.. then I got a new bottle because the old one was empty, and suddenly, no growth, beard algae, black beard algae, plants died off... Now I switched to Aquarebell, I fertilize daily, and now, it's amazing, I'm… (read more)

Great fertilizer, plants took root right away and look really well nourished, no wilted or weak leaves

This is my 2nd bottle of NPK fertilizer and I highly recommend it. My fish stocking is rather small, which is why I bought the fertilizer. My plants reacted immediately: pale red plants turned deep red, the tips of the heteranthera zosterifolia became big and spreading, and so on. Never without it… (read more)

A good all-in-one solution for NPK supply with a higher potassium share. For potassium- or phosphate-limited fertilization, however, the Spezial fertilizers (single components) are more suitable, since they let you specifically boost the individual parameters.

Good macro fertilizer for raising the values in line with consumption. Easy to dose, whether weekly or daily. Fast delivery as always. Thanks

Aqua Rebell Makro Basic NPK is perfect for use with a dosing pump. Aqua Rebell Makro Basic NPK is safe for shrimp in a well planted aquarium.

I've already ordered this fertilizer several times and will keep ordering it. Plants grow very well. Algae growth has gone down a lot.

Good product and arrived quickly!
I'm happy to stay loyal to this shop and will shop here again when needed. Keep it up.

I've been using the fertilizer for 1.5 years and can recommend it without reservation! No problems with shrimp, either.

Super fast delivery, well-packed products.
Immediate free replacement in case of a defective product or a wrong delivery.
Very good and clearly laid-out shop design and moderate prices.
It's a real pleasure to shop here!
A clear recommendation...

A very good, affordable NPK fertilizer with a good composition, economical in use, unbeatable in combination with the full iron fertilizer. I tested the fertilizer in three of my tanks and achieved very good results

It contains exactly what it says on the label, you get service and tips with it, and the price is OK. I use the fertilizer in 2 tanks and am satisfied

In my opinion the best supplemental fertilizer for the aquarium. Works very well with the doser... you should get it too. The plants grow very well.

Great product and fantastic customer service. The included dosing pump makes fertilizing child's play. I'm absolutely thrilled with you guys and your products!

Great products since I started using Aquarebell - algae-free and great growth. Really fantastic value for money.
That's just what you want.
Thanks!

Great macronutrient fertilizer, but unfortunately I have to switch to the individual components because of too high a potassium concentration in the tank despite partial water changes. Thread algae galore, but happy plants. ;-)

My plants are going wild and there are no signs of algae! I combine the fertilizer with the iron fertilizer from Aquasabi.
Shipping was damn fast as always :)

Great fertilizer products. Highly recommended, well-matched complementary products (other fertilizers). As always, excellent advice (details for exact calculation) and super fast shipping.

Perfect mix - practical dosing

I noticed significantly better growth

Absolutely convinced by the product! Plants are developing excellently.

Great product

I'm extremely happy with the product.

Worked well for the plants.

Aquarium keeps getting better.

Great fertilizer, nothing negative to report. I'll stick with them. The only thing I'd wish for is a substrate fertilizer from Aqua Rebell ;-).

EXCELLENT!!! I have a 200 liter tank, use Makro Basic - NPK, Mikro Basic - Eisenvolldünger and Makro Spezial - N and everything I put in grows, but you have to take your time and find out the exact dosage, otherwise the algae show up. I'm thrilled!!!!!!

Good product, very happy with it. Very fast shipping, DHL tracking by e-mail.
I'll recommend Aquasabi to others.

Great product, very user-friendly! Also super fast shipping!

Good fertilizer! VERY good value for money! Great :)

very good fertilizer and easy to dose

I switched my fertilization system completely to AR 6 weeks ago, after even "very fast-growing" plants had only been growing moderately, but with plenty of algae. Now I use Basic NPK, Nitrat and the Eisenvolldünger in 2 aquariums. At the beginning there was a real boost in algae, so I already had… (read more)

flawless
switched over to daily fertilization
don't use it every morning with a syringe, but about every 2 days as specified
great

Simply sensational!

Well tolerated and effective. Great

Very interesting price-wise, but after approx. 3 weeks of adding the fertilizer amount daily I had enormous algae growth, I've now switched to Easy Life and everything is growing great

A very good combination with Mikro Basic Eisenvolldünger and Makrospezial N. I have a 250 l tank with a small fish stock, and fertilization is sufficient here. My plants thank me daily with very good growth and color, and they photosynthesize like crazy after a few hours. (0.5 W/l)

I can't really review it because I'm using it for the first time. I relied on other people's reviews and opinions. What I would like to say already, though, is that it would be nice if you could also buy an attachment or something similar (a screw-on measuring attachment like I know from the Drak… (read more)

Excellent as always, can't say more than that, thank you very much

Hi.
I'm really convinced by the product. This is already the second jug I've ordered from you.
My plants are going wild. Really awesome stuff.
Keep it up.
Greetings from Berlin.

Very good product, but since I want to fertilize more specifically, I'll order NPK separately. In general, the Aqua Rebell products are excellent in terms of dosing, cost-effectiveness and uptake by the plants. Recommendation rate 100%

Great fertilizer. Everything grows splendidly and the price is right, too. You should just make sure that potassium doesn't accumulate.

I had better experiences with the Tropica fertilizer, so I'll use that again in the future. Note from Aquasabi: You should not have used Makro Basic NPK only in combination with the pure iron fertilizer, Mikro Spezial Eisen. In that case, very important micronutrients were lacking for a long time.… (read more)

Ideal for topping up nutrients at the water change! Tip: afterwards, use the Estimate Index dosed as NPK....

My opinion of the product is very good. Plants get a boost. Not too much, otherwise thread algae.

Everything was perfect, would order again anytime

Serves its purpose to my satisfaction

Just stick to the dosing instructions. In combination with other AquaRebell products, I was able to achieve very good and stable conditions in both of my freshwater tanks. Highly recommended for mosses.

Great fertilizer at a super price. Delivery was very fast as usual and the advice was competent. Thanks!

Very satisfied with the product so far. I'll definitely buy there again :)

Great product! Since I started using this supplemental fertilizer, plant growth has improved a lot.

Totally okay, the fertilizer is really recommended. You do have to test a bit until you find the exact dosage, but then very good plant growth.

Unfortunately my son, who owns the completely algae-covered aquarium, is too lazy to do regular water changes. As a result, the fertilizer doesn't work the way it normally does (I know from word of mouth that it's great).
So the problem here isn't the product, but the user.

very fast delivery as always

Great plant growth. Fast delivery

Since I started using this fertilizer I've had fewer problems with algae. The plants also grow much better!

Awesome! My Eleocharis is finally growing!

Very fast shipping, flawless products. AR fertilizers are a good and cheaper alternative to comparable and
far more expensive products,
As always: full marks for Aquasabi.

Good, ready-mixed fertilizer mix in compact packaging.
Does what it says on the tin.
However, for a 200 liter tank with a CO2 system and lots of planting, I recommend
just buying the 1 liter bottle right away.

I fertilized with Elos before and didn't come anywhere near this result. The value for money is right. I've never owned such a good-looking aquarium.

good product, the plants grow great

great product, fast delivery

..solid fertilizer at a good value for money.

A very good product. Highly recommend

I've been using this fertilizer for a few months now and I'm very satisfied. My plants grow very well and look very healthy, too. Something I could never say before. Since then I also haven't had any problems with algae of any kind.
Highly recommend

The plants are thriving and have a rich green.
Finally I've found (in combination with Mikro Basic - Eisenvolldünger) a proper fertilization program.

Great fertilizer, plants grow like crazy

What can I say ... does what it says on the tin !

After long-term use of this fertilizer, I came to the conclusion, when comparing, that it's better to dose the nutrients individually. By contrast, the Makro Basik fertilizer caused algae growth, which is probably due to a poor salt mixture

Very good - highly recommend!

Everything's great, would buy again, thank you so much!!!

Very good liquid fertilizer, highly recommend

Plant growth, which used to just putter along, has improved enormously with Makro Basic NPK.
During maintenance (every 14 days), meaning thinning out and trimming, I can now barely keep up.
Then again, I run 1 watt/liter.
The product is my first choice!

I'd like to thank you not only for the excellent fertilizer from Aqua Rebell, which gives me a lot of joy with my tanks, but also especially for the delivery times and customer service that Aquasabi has to offer, since I unfortunately can't find a guestbook or the like to share my absolutely… (read more)

Ordered Sunday, delivered Tuesday, perfect. Now after 1 week the plants are going wild and crazy.

Because of the short period of use, I unfortunately can't say much about it yet. A plus for me is the fact that the fertilizer is colorless and odorless.

Everything perfect, except maybe the price...
Best, Jürgen

Ordered early - the next noon the mailman was already ringing the bell with the package - EXCELLENT.

In combination with a good micronutrient… (read more)

Great fertilizer - everything grows and thrives - no more thread algae...

Great for my shrimp tanks!

Great product, after a good 14 days I could wonderfully watch the plants recover. Also, "Korsiert" "produces oxygen" like crazy. I'm so happy. Delivery excellent as always.
Combine this liquid fertilizer with other fertilizer and your plants will thank you.
Highly recommend.

Great fertilizer and exactly what my cube was probably still missing.
Since the ratio of N to P to K seems to be right, there's plant growth galore, no more green glass and the thread algae are history, too!
And at a fair price!

Very happy, super price for such high quality! Thanks

very good product, unfortunately not available like this in Switzerland

I use the fertilizer together with Easy Life ProFito (1 ml ProFito + 2 ml Makro Basik NPK / day in a 125 l aquarium following the PPS Pro at flowgrow) and BioCO2. I should probably start reducing the dose soon, though, because otherwise my tank will become overgrown... ;-)

Fast delivery positively surprised me

I can't recommend this fertilizer highly enough, the value for money is just perfect

Highly recommend Aqua Rebell! I'm satisfied!

Everything worked out great, super fast delivery!

in combination with the Mikro Basic Eisenvolldünger 500 ml from the same manufacturer, my plants grow almost as fast as the mega-fast delivery at aquasabi

very fast delivery and, from previous experience, a really good fertilizer

Good product, finally got my desired water parameters and a super fast delivery on top of that!!!
Keep it up, it's a pleasure to shop here!

Very good fertilizer, everything grows like crazy....

Plant growth is finally taking off!!

Great plant growth for little money! I won't use anything else in the future.

Good fertilizer, everything has been greening up nicely since :)

Since using it, my plant growth has increased enormously. Algae have disappeared except for a small remainder.
Completely satisfied with the product.

Very good product with very convincing results ! I won't use anything else anymore !

Well, I can recommend it 100%, the plants grow like crazy, I never really had luck with aquarium plants but now everything is great... 5*****STARS

Delivered quickly as always. Great supplemental fertilizer. Everything grows like crazy!

Super fast delivery:-) Highly recommend this fertilizer, especially if you want to fertilize daily like I do.

Very good product that I'm very satisfied with. My plants grow very well and fast with this fertilizer.

Great fertilizer, highly recommend

Great product. Works well.

Great stuff! My plants are growing noticeably better now.

Very fast delivery, excellent product

Excellent quality, my plants are finally growing really well again.

I've had problems with black beard algae for a long time. The information that a deficiency of macronutrients could be the cause is what made me buy this product. After several weeks of use, I have to say that nothing has changed regarding the black beard algae. Of course, that doesn't speak… (read more)

Very good product and very low price!

Ever since I started using the fertilizer, my plants grow much better and look even more natural. Great fertilizer

My tank is finally turning into a jungle !
The fertilizer is great, everything is growing and thriving, except for the annoying algae, which are finally disappearing. Easy to dose thanks to the dosing pump. Many thanks also for the lovely plantlets of various plants!

Would order from you again anytime

Very good product, unfortunately my plant growth was slightly stagnating during the time I was adding it.

Great stuff, I've been using the fertilizer for a month now and I have to say that I'm completely satisfied. Delivery was also quick and speedy. Thanks again.

Very good plant fertilizer and a great value for money.
I'm happy to keep using it.

I've been fertilizing with the NPK for over two years now and I have to say, it's not only recommended for beginners. EXCELLENT!

Good fertilizer. Easy to dose and transparent thanks to the exact list of ingredients.

Really great product, highly recommend!!

I've been using this fertilizer for a good 3 weeks now and I'm convinced by its effect.
I'll keep buying it.

Super fast. Thanks for the little extra. Fertilizer will be tested as soon as the CO2 supply is secured.

I bought the NPK fertilizer because an aquarist in a forum told me about it and I had been struggling with poor plant growth (caused by nutrient deficiency) and algae for some time anyway. Using it has paid off very well so far. The plants are growing and thriving again and the algae are in… (read more)

Okay, anyone who can read (on) is clearly at an advantage. It also says further down that you have to order this pump along with it.

Excellent, this NPK fertilizer lives up to its promise

For anyone who doesn't want to wrestle with chemicals, the first choice.

Product arrived within two days after payment. Lives up to its promise, my plants are growing again and I have to get out the scissors every week. Extremely satisfied and I will order it again.

I have nothing but good things to report! Combined with the Mikro Basic, the plants simply grow great!

The product reliably replenishes macronutrients. In combination with CO2, it works wonders for me.
The shipping is absolutely commendable: fast and uncomplicated. Nothing to complain about.

I've been using the product for three weeks. Water parameters EXCELLENT.

The plants are thrilled

Service is great, and my plants seem to be slowly shaking off their growth problem ;-) I'm still not quite sure about the dosage (maybe a bit more?), but it works really well, also thanks to the dosing pump. I use it in combination with Profito. I still have some algae (thread algae), but I hope… (read more)

Great fertilizer that perfectly fixes the slight nitrate and phosphate deficiency in my tank!

Very good product. Together with the Mikro Basic I finally have great plant growth, and my big cyanobacteria problem is finally under control (in my opinion) (also) thanks to using the Makro Basic NPK.

Very good and effective in combination with the Makro Basic Eisen...

Great! My aquarium really needed the fertilizer. Now everything is growing like crazy again, and the algae are in retreat. Really easy to dose with the pump, too. By the way, the delivery was lightning fast as well. Would order again anytime!

I used to always mix the solution myself, but with AR NPK I fortunately don't need to anymore!! Totally satisfied and the fertilizer is every bit as good as the other commercial ones!!

The fertilizer lives up to its promise, I use it together with the Mikro Basic - complete iron fertilizer and am more than satisfied.
What I like best here is the service. Ordered on 10/22, shipped on 10/23
and had my order in my hands on 10/24.
Truly thrilled, keep it up

Great stuff! Plants are growing, shrimp and fish are all living happily

This is the best thing I've bought so far, my plants now look lush green and I don't have to worry about algae anymore. Whether that's connected to this fertilizer I don't know, but it's the only one I use now.

Very good, especially practical with the dosing aid!

I'm satisfied with it :-)

I think this fertilizer additive is worth it

Great product, thread algae have receded and the plants are growing over my head! Highly recommend!

I'm still happy with it and will stick with it.

Great product. Plants are thriving beautifully. The dosing aid is a great thing.

The fertilizer fits my needs exactly.
Everything is growing excellently.

Torn, because I had hoped that adding fertilizer daily would not only make the plants grow better (which is the case), but also make the black beard algae disappear, which unfortunately is not the case.

I'm satisfied and, what's even more important, so are my plants :-).

With this fertilizer it's harder for me to judge how good it is. That's due to the fact that previously I did fertilize potassium and nitrogen, but separately, and phosphate not at all. Subjectively speaking, I'd say my plants feel like they're growing at least as well as before, but with fewer… (read more)

I'm very satisfied with the NPK fertilizer. It brought a real turnaround in my aquarium. The algae are retreating and the aquatic plants are now growing much faster. I'll stick with this fertilizer.

Highly recommend! I had a major algae problem, but thanks to the fertilizer and the iron fertilizer together I'm slowly getting it under control again!
Thanks Tobi

Good fertilizer. I'll continue fertilizing with the Makro Basic NPK. Among other things, it has helped contain my black beard algae problem.

Good ratio of the 3 nutrients!

Hello,
after almost 4 months of use now, I'm very satisfied with the product

Very fast shipping, good value for money!
Very satisfied!

I had big problems with algae of all kinds. With Makro Basic NPK in combination with EasyLife Carbo and a slight overdose of a complete iron fertilizer, the algae have almost completely disappeared. Very satisfied!

When algae problems spoiled the "aquarium" hobby for me, I heard about Makro Basic NPK and tried it.
Since then I swear by the stuff: no more problems!!

Plants seem to be growing well

I think this fertilizer is great, I'm very satisfied with it.

Excellent quality all around. My tank just took off. The CO2 set looks great too.

Have been using the fertilizer for a short while now.....
Plants are growing and look nice and green ;-)

Excellent product! Plus fast shipping and impeccable service!

Everything is great! I can "warmly" recommend both the macro and the micro fertilizer.

Very good, also well suited for beginners! Easy to dose!

Hello Tobi, I'm very satisfied with the fertilizer, but I have to dose it a bit sparingly and add some potassium.

Hello Tobi,
I'm completely satisfied.
Fits great.
Regards

I had big problems with thread algae and black beard algae.
Since I started fertilizing with MacroBasic NPK, the problem has disappeared.
Highly recommend this fertilizer !!!

I'm very satisfied so far. However, despite Makro Basic my tank still needs additional potassium, which I make myself from potash.
