I've now had in-vitro plants for approx. 10 weeks and by now I was able to fill 2 aquariums with them, 70 and 35 l, and the plants have reached a nice density and a height of approx. 15-20 cm. Whether that was due to the liquid CO2 I added, the oxygen via oxydator, or the occasional addition of this Flowgrow fertilizer, I don't know. But I have the feeling that the roots of the shoots grow better and faster in the sand since I've been adding flowgrow daily. Have now been adding it daily for approx. 7 days and notice a difference compared to the other aquarium.

It's probably rather difficult to prove the effect when you use it from the start. Would almost need a control tank :) But I'm almost sure that the fertilizer is why the algae receded in the last 7 days

great again
everything was very fast
the fertilizer is great like the rest
thanks Asabi team

I've only been using the Flowgrow fertilization for a short time and already have to say that you can already see in the plant growth that the fertilizer has a mega effect.
You can already tell that the newly grown plant parts grow stronger and faster .
The color of the plants has also become stronger .
Especially the leaves of my plants that are just coming in are getting bigger and are finally getting their beautiful shape.

Fast delivery, as always! Product as expected. The price for 5 liters is of course better than for a 1 liter container!

With this product, budget-friendly iron fertilization is possible. The micronutrients are weakly chelated, which is why they are only available for a short time. This reduces the risk (with otherwise normal water changes) of iron overfertilization and the associated tendency toward red algae.

Very good, easy-to-use fertilizer. I use it with NPK Makro from Aqua Rebel. My plants are growing very well. Time to play gardener

I think the product gives the plants an extra kick. Plants look healthier and stronger. Would definitely recommend the product.

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

Great fertilizer and I can see it in my plants. But anyone who uses a UV-C clarifier should rather choose a different fertilizer. The light attacks the chelate and it's very weak in this fertilizer. Your iron oxidizes faster and becomes unusable for the plants.

This fertilizer really works very fast. Especially the red plants look noticeably more colorful and stronger. I've been using the fertilizer for 2 weeks now and am curious about what's coming.

Best additional micro fertilizer I've ever had (measured by plant growth). Used in combination with Flowgrow Estimative Index, Flowgrow Spezial N, Flowgrow Spezial Eisen and Flowgrow Basic Eisen.

Always use this product because the plants always look great with it. Highly recommend. Fast delivery as always from Aquasabi.

For me this is the best brand ( Aqua Rebell ) of fertilizer.
The plants look great, I always start with half the dose first.

The plants grow like crazy.
Easy dosing since everything is described exactly. I can recommend the fertilizer to everyone.
Keep it up

Also use the fertilizer as a daily fertilizer and can't complain, beautiful red tones in the plants since then.
Highly recommend it!

Well, I think this fertilizer meets my requirements. It's best used daily and has a high iron content. It lasts me half a year in a 600 l tank. I just find the manganese content too low, no idea why that is, but in the Basic iron the ratio is Fe 1 to Mn 0.5 mg/l.
With the Basic iron I would need 4 times the amount.... maybe someone can explain this to me

Normally I mix my own macro fertilizers. With micro fertilizer, unfortunately, that doesn't make sense because of the many components. Together with Mikro Basic, this fertilizer is a great addition. In my opinion a must, even for easy-to-grow aquatic plants! The amount of fertilizer is negligibly small; I dose approx. 0.5 ml on my 60 l Nano Cube, every other day. After the water change I use Mikro Basic at a greatly reduced dose, approx. 2 ml per 60 gross liters. I'm very happy, the fertilizer is worth its money and goes a very long way.

Can't rate it yet since I've only just received the fertilizer. Delivery is very fast, which was already good.

Thank you very much first of all for the hassle-free transaction - your shop is excellent.
I've been using the micronutrients for almost 3 years now and I'm thrilled. They're the icing on the cake in my tank, the plants grow much more beautifully and evenly.

All deliveries I've received so far arrived promptly and securely packed. The aquatic plants were in absolutely excellent condition.

The best plant fertilizer I've ever had!! My plants grow like crazy, and as a result there's no algae growth. Very economical with the matching dosing pump. Highly recommended!!

After plenty of "tests" with other products and "measurement series", still thrilled. That's why I'm now getting the 5 l version, since I need a significantly higher dosage to reach the desired measured values right after dosing. Because of the lack of stabilization, long-term measurements aren't very meaningful anyway. EXCELLENT

but unfortunately not good for my tank.

I most recently dosed 5 ml per 150 l daily and didn't come anywhere near the intense color results I had achieved with 2 ml daily using the Basic iron complete fertilizer.

So unfortunately the fertilizer isn't for me.

After a lot of back and forth with various manufacturers, finally a fertilizer that clearly states its contents and amounts and lets you control the fertilization very well and precisely.

My tanks had been running pretty well for a long time. Since I've also been dosing the Flowgrow, the plants simply look even better.

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!

In my opinion this fertilizer is a very worthy substitute for its more expensive competitor! I dose it daily and my plants grow very well!

I use the Mikro Spezial Flowgrow in combination with the Mikro Basic Eisen and am more than satisfied!
All plants are growing like crazy!

Brilliant daily fertilizer. LIKE all products from AR, which I've been using for five months (things really take off with them), this one is worth its money too.

I'm now using this fertilizer as a daily fertilizer, the dosage is 7 ml for a 350 l tank. I've only just started working with this fertilizer. We'll see what it looks like in a few weeks.

Verry good product, plants react fast on this products. You can give precise amount for your aquarium.

I use:

Spezial N
Spezial K
Spezial Licht
Spezial Flowgrow
Spezial Eisen

(And Co2 ofcourse)

In most other products nutrition are a lot together so if you want to give one thing more you have to give everything more. Aqua rebell use also a few products were nutrition are togheter but is macro or micro and belongs thogether so no problem.

With the products from aqua rebell you can give all in the good amount and play whit the product and see whats best for you

I used the use the more expensive products form ADA, and i have to say that i think the product from aqua rebell are better. I am verry verry pleased.

I've been using the FG Spezial for several years now and am still completely satisfied. In my opinion the best micro fertilizer! I use it together with the Eisen Spezial and in combination with the NPK fertilizers and N Spezial. The interplay is flawless and the plants are grateful for it!

Finally a fertilizer with clear information on contents and amounts, and not an all-in-one fertilizer without any information whatsoever. Also very nice: finally a sturdy bottle and not soft PET. Hopefully the effect in the 180 l tank will show.

After my first aquarium got overrun with algae and my plants withered, I was close to despair because I couldn't get it stable. My problem (with other fertilizers) was also that I never knew exactly what I was actually pouring into the aquarium at what concentration, and all I did was measure. Then I came across the Aqua Rebell fertilizer. What can I say, simply brilliant. Finally an exact list of the nutrients the fertilizer contains. I'm very satisfied with the plant growth. They took to the fertilizer gratefully right away and now shine in a lush green, and the red plants have never been so intensely colored. Today my aquarium runs stably and I can finally enjoy it. xD
I highly recommend this fertilizer, especially for beginners.

Very fast delivery and well packed!
Thanks Aquasabi!

I use this fertilizer in a low dose with daily application and enjoy flawless plant growth! However, I would only buy small containers regularly so that the nutrients always reach the plants "fresh".

A very good fertilizer for me. The plants show great coloration and good, healthy growth. But you should have a certain eye for your plants and not just start dosing blindly. I adjust the fertilization practically daily. I have certain plants that I treat as indicator plants and adjust the dose accordingly

After just two days of use at the standard dosage, my plants showed more vivid colors, especially Rotala species. I couldn't achieve this with a more strongly chelated complete fertilizer.

The product lives up to its promise.
Very easy to use. Easy to dose in combination with the pump.
Always happy to order again.

This is the third liquid fertilizer I've bought, all different brands, and I have to say, I'm sticking with this one.
The plants grow great, even without CO2 fertilization.
The colors are much more intense after just 1 week of use and my Helferlie plants are curling up incredibly nicely.
Highly recommend!

Great fertilizer, plants go wild. For me, though, I have to use double the dose, otherwise it's too little and the plants get stunted. Whether it's the boron or manganese, I don't know.

For me the perfect daily fertilizer. Since I'm busy with the aquarium every day and value magnificent plant growth, this mildly chelated fertilizer suits me just fine. I previously used Easy Life Profito, but I wasn't satisfied with that fertilizer; rather unsuitable as a daily fertilizer, and the product doesn't state the exact input of nutrients.

The Mikro Spezial Flowgrow isn't fundamentally declared as a daily fertilizer, but that's how I've been using it so far with the greatest success.

What more can you say, the fertilizer is definitely worth its money. I'll keep buying it.

Well, I have to say I'm very surprised. After so many "very good" reviews, I thought I'd order it too. Now I fertilize once a week with the AR Basic iron complete fertilizer and daily with the Flowgrow. WOOOOW what a splendor of colors.... My red plants look sooo great and that after only 2 days of use. I hadn't paid any attention to whether anything changed. But when I had to handle something in the aquarium after 2 days, I took a look inside and my first thought was "Wow, what a beautiful red" Until I remembered that I've been dumping in the Flowgrow daily for 2 days!

So 5*

Great fertilizer. I've been using it for several years now.

It works excellently! Everything grows and thrives. From now on only Aquarebell!

Mikro Spezial is a good fertilizer. Highly recommend.

Very good fertilizer! Makes everything shine in full splendor!

Really helps better than the other fertilizers! I didn't believe it at first and then I got the result! Great fertilizer!! Highly recommend!

I can't really judge it ! Good plant growth depends on several conditions. No improvements at the moment ....

best fertilizer - fast delivery

Very good daily fertilizer. Plants definitely grow better with sufficient light!

Plants grow GREAT; what more is there to say? :)

very good fertilizer for daily fertilization. Would buy again anytime.

What can I say............ the plants just keep growing and growing. Seems tailor-made for my tank!!! Now becomes my standard fertilizer

SENSATIONAL!!!! The fertilizers are AWESOME!

A good fertilizer, but i bit, in my opinion, too strong and concentrated. I had to change to a drop bottle, so i can easily adjust the dose that i want.

Not bad as such, unfortunately insufficient growth readiness of the aquatic plants, algae were very happy about the quick availability, so only 3 stars.

After regularly determining the consumption of the individual nutrients, my aquarium is running very well. I use Mikro Spezial Flowgrow in addition to Spezial N for daily iron and trace element fertilization. The plants no longer show deficiency symptoms since I've been using the Aqua Rebell fertilizers specifically. Shipping and delivery are super fast.

Great iron fertilize,r but not practical in small aquariums. You have to calculate with drops, or to dilute it.

Everything excellent as always, thank you and see you next time. Best regards, Jens

Plants look really good, I use the whole thing in a high-light tank

Very good fertilizer, especially with daily application.
With the Flowgrow everything grows like crazy!

Totally satisfied

Everything great, would order again anytime

Very fast delivery, good product!

Used by me in addition to individual fertilizers as a daily fertilizer – very good results.
Super fast delivery

very fast delivery as always

Great fertilizer! Everything grows well!

I've now been using the product repeatedly and am still very satisfied with it.
Very well suited for daily fertilization.

My plants are now growing like crazy and shipping was lightning fast. Highly recommend!

The product is sensational at the right dosage and in combination with other AquaRebell products.
It's equally suited for beginners and advanced aquarists.

I'm very satisfied.
You can't shop better. Quality and service are unique.

perfect nutrient availability with my water parameters.

at first I couldn't get along with it, but now that I know how to dose it, I'm super satisfied. I've never had plants this red, so I can recommend this fertilizer without reservation.

After a short transition phase for the plants, beautiful and healthy growth.

Good advice as always. It flows ;-).

great product fast delivery

Bought this fertilizer together with the Macro Basic and can only say that I'm completely satisfied

Highly recommend

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

Since I started using this fertilizer I've had strong green and red leaves on the plants.
Very satisfied with it.

Best regards
Alex S.

Hi!

Everyone knows the Aqua-Rebell products are excellent, but shipping within 24 hours is simply awesome! Hats off!

Similar to my namesake (Joachim), I too switched from EL Profito and EL Ferro to this product with daily dosing and haven't regretted it, quite the opposite. In a well-planted and well-stocked tank, heavy thread algae promptly appeared after every EL Ferro dose before; with the new product they only appear when I neglect tank maintenance, otherwise everything's great!
Those with heavily stocked tanks don't necessarily need to add N and / or P, in my opinion, but trace elements and some K, as apparently contained in this product in a fairly balanced way. Stability with low consumption after 2 months now: flawless. Fertilizing according to the instructions for use - works.

A fertilizer I can highly recommend, better plant growth was visible as early as the 2nd day after the first application in the tank.
Lightning-fast delivery by "Aquasabi"...Simply the best. :-))

Great product! Since I stopped using EL Ferro and Profito (good in themselves too), each dosed weekly, and switched to this one with daily dosing via a dosing pump, everything still grows well, but the algae (thread algae) stay away. My red plants have really vivid color, all look healthy and the stem plants have very short internode sections. A+.

I bought the fertilizer because my Mikro Basic was all gone. I dose it according to the instructions and have no problems.

Everything I order here is great every single time!
Thank you very much!!! =D

Flawless as always and super quality

great, my plants are growing again

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

Everything is very good. This stuff is making my little underwater world green up. Respect for that.

Really excellent fertilizer, nothing to complain about

Great fertilizer! I've been using it for a week in combination with Makro Basic EI and since then the plants have been assimilating like crazy. I can practically watch the green algae disappear. Great product! Thank you very much!!!

We have now ordered the Mikro Spezial Flowgrow from Tobi for the 3rd time and are more than satisfied with it, our plants grow very well, even difficult plant species are supplied with nutrients excellently with this liquid fertilizer.

Tobi, respect, keep it up....we'll happily order from you again

Very quickly available fertilizer, unfortunately a bit weakly chelated in combination with my HMF and EI-style dosed macros, therefore in this particular case with a shrimp-toxic side effect.
Comment Aquasabi: All Aqua Rebell fertilizers can be used absolutely without concern, even with shrimp. The Mikro Spezial Flowgrow in particular can be used with invertebrates without any problems. The weaker stabilization has no influence on compatibility with invertebrates. Numerous tests have shown that absolutely no problems are to be expected here.

Hello,
I've tried many fertilizers and stuck with this one! Great!
Best regards

Made exactly the right choice with the Special. With my acidic pH, no micro fertilizer has worked better.

Super fast delivery, great fertilizer!!

thank you very much, everything went great, fast delivery! the plants say thanks :) Best regards

Very good fertilizer, I've achieved the best results so far with the Spezial

My plants are happy about the extra portion before getting up :)

Hello,
I'm still experimenting. The leaves developed a brownish coating that dissolved after 3 weeks.
I don't want to say anything wrong, I still need a bit of time. Things are slowly moving forward, though.
I'll get back to you.

Best regards
Waldemar

Had previously also used the Mikro Basic iron complete fertilizer and am just as more than satisfied with the Spezial Flowgrow!!
