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

Product meets my expectations. Delivered quickly, everything great. Dispenses exactly the way you want it

Basically I think the pumps are great, the dosing is accurate and the quality seems good too. Unfortunately they didn't fit the containers of the Aqua-Rebell blanks perfectly for me and always sat a bit crooked on the bottle. Still, everything was sealed tight and they did their job.

For 500 ml containers, cut it off, screw it on, start fertilizing, three two one

The product is as described - there were no problems with shipping

I don't need 0.1 ml dosing, so the dosing head is pretty good for my needs. It also stays sealed and doesn't leak over time. Only one star minus because it sometimes sticks a little if you haven't used it for a few days.
Otherwise I highly recommend the dosing head.

Very well made, easy to use, but sometimes only half comes out on the first pump.

Reliable dispenser. Unlike the pump heads on the Dennerle fertilizer bottles, it hasn't happened to me so far that this one gets clogged. I haven't measured whether exactly 1 ml really comes out. But since using the fertilizer as specified works well, I assume the amount is really correct.

I find the product tip-top. Highly recommend it. Great for dosing. Can also be used for other bottles.

another great delivery, fast and good

the pump is perfect for fertilizing

happy to order again

thanks, dear team

Does what it's supposed to, I've had the dispenser in use for 2 years without problems. Great relief. I'd buy it again for any new fertilizer

If about 2 ml are needed for the daily dosing of NPK liquid fertilizer, this amount can be handled easily with the dosing pump. I use several liquid fertilizers from Aqua Rebell, and the dosing pump fits perfectly on the 500 ml as well as the 1000 ml bottles. Simple and clean to use. Highly recommend it to everyone, electric dosing pumps are not more accurate either and cost a lot of money.

Dispenses pretty much exactly 1 ml per pump stroke without ... With daily fertilizing using various Aqua Rebell products in several tanks, a real relief and time saver.

The pump dispenses more than 1 milliliter.
For precise daily fertilizing, the pump is unsuitable for me.
So I'm going back to the tried-and-true measuring cup.

Dispenses essentially fairly accurately (use in aquariums > 45P easily doable; in smaller aquariums a drop dispenser should be used). Solidly crafted, which makes it very durable.

After cutting the tube to fit the 0.5 l bottles, it works great. Easy dosing of small amounts. Exactly what you need, because the whole bottle can be emptied too.

I got these pumps for precise dosing, unfortunately they don't fulfill this purpose, the delivery volume for me fluctuates between 1-2 ml...

Great product, the length is adjustable and it also has the lock function. Value for money very good. Great workmanship.

The pump works as expected. There's not much to say about it.
I'd buy it again. The tubing is nice and long and can be shortened without any problem.

The thing works, there's nothing more to say about it, but I'm being forced to write more. So: it really does work.

Super fast delivery, 1 day after ordering. Works flawlessly. Inexpensive, easy handling, everything great. Keep it up. . . . .

Pumps and does what it's supposed to - what more is there to write about it.
Length can be easily adjusted to the size of the bottle

With the pump dispenser, fertilizing is much more practical than with a pipette or a measuring cup. However, you have to cut the suction line to the right length yourself.

It fits perfectly and can even be cut to size individually! Fits perfectly with AquaRebell's fertilizer! A must for every aquarist!

Using a small, precise 1 ml syringe from the medical field, I measured the output volume of the dosing pump several times, after I found some traces of beard algae in my small 20-liter aquarium. These can often be traced back to a disproportionately high dose of complete iron fertilizer.
That seemed odd to me, because I only fertilize 1 ml once a week, more rarely 2 ml as needed, of AquaRebel Mikro Basic Eisen. So really not much.
My measurements with the syringe showed that the dosing pump's output varies between 1 ml and up to almost 2 ml. With nitrate and potassium fertilization or in large aquariums this inaccuracy may not be so bad, but in my 20-liter tank this inaccuracy is noticeable.
I now fertilize iron only with the precision syringe.

The delivery was super well packed and arrived safe and sound together with the fertilizer and plants. What more is there to say, does what it's supposed to and makes the dosing of the daily fertilization easier.

Works as described, although I'm a bit unsure whether one press is really 1 ml. But those are just minor details.

This way, fertilizer is dosed quickly and easily. The pump is very inexpensive here at 1€.
Highly recommend.
If needed, the pump tube can be shortened. For my Aqua Rebell 500ml it was a bit too long. For the 1000ml the dosing pump fits perfectly.

The first stroke is extremely inaccurate. Have 3 dosing aids (iron, n, phosphate)
First stroke:
Iron 0.4 ml
Phosphate 0.8 ml
N 0.3 ml
I'm now going to switch back to dosing by syringe.

I like the dosing attachment a lot. Makes measuring much easier. Unfortunately a bit more than 1 ml comes out per stroke. But we've adjusted to it now.

I was pleasantly surprised at how little the pump tends to drip.
As mentioned before, it's moderately precise at approx. +- 10 %. For larger amounts, large syringes and measuring cups are better suited.

I got the pump for the 250ml containers. After shortening the tube at the bottom, it fits great.
However, more than 1ml comes out of the pump per stroke. I measured it and it's approx. 1.167 ml per stroke.
Since I normally administer 12 ml, 12 strokes give me approx. 14 ml.
Once you know that, it's OK though.

The dosing pump simply fits the Aqua Rebell bottles ideally. It also makes dosing the fertilizer child's play. The value for money hardly needs highlighting at a cost of just 1 €.

The dosing pump works as it should. Shipping was very quick as always, as we're used to from Aquasabi. What more could you want?

I'm now trying to describe in twenty words that the dosing pump does exactly what it's supposed to. It pumps! :-P
The amount is right and it can be locked by twisting.

What is there to say. Does exactly what it's supposed to. It pumps the fertilizer when I press it. Thanx

Extra long tube, can be perfectly adjusted to any bottle. Dosing works very well and evenly, every day, so very well suited for daily fertilizer

I use this dosing pump for the Aqua Rebell Makro Spezial N fertilizer. Workmanship and operability are very good. Maybe worth mentioning for some: the pump dispenses approx. 1.2 ml per pump stroke. I'm happy with the dosing pump!

I think you can't go wrong with this product. What I like is that the dosing is exactly 1 ml

Thank you very much .
Very very fast shipping .
Perfect quality .
Will definitely order again.
😊 😊 😊 😊 😊 😊

This way you can quickly fertilize your aquarium "just like that", without much time spent.
Simply after the light in the aquarium turns on in the morning, briefly add the required pump strokes to the water - done.

Does exactly what it's supposed to. Dispenses extremely reliably and accurately.

As always with Aquasabi, a great product. Fast delivery and decent service.

I did have to shorten the tube a bit for a 500ml bottle, but otherwise it does what it's supposed to :) Highly recommend.

The item arrived safely packed and really makes fertilizing easier. Only flaw: on the first pump stroke it seems like it doesn't draw the full 1ml.

Great product.
And a big compliment to the Aquasabi team, super fast shipping.
I only buy from you guys now.
Keep it up.

The dosing pumps are quite practical , one stroke = 1 ml. That makes the (already not very time-consuming) fertilizing even faster.

Easy to use, was exactly 1 ml. They were just a bit too long (for the long Rebell bottles), but shortening them was quick.

Fits the Aqua Rebell bottles, is leak-proof. You don't need more than that. And for the price you don't have to think twice.

Delivered very quickly and the packaging was flawless. Sturdy and works. It can be locked by turning it right and left. Would buy again.

Simply practical to use. It also makes it easier to stick to your fertilizing schedules.
0,50€ would have been enough, though ;)

I ordered the dosing pump along with my 500 ml fertilizer bottles, as recommended. Unfortunately, the suction tubes are much too long, so I had to shorten them. If I want to switch to larger bottles now, I'll have to order them again. That's a shame.

Clean solution, makes fertilizing fun. I highly recommend this product. I have one mounted on all of my fertilizer bottles.

Great tool for getting the fertilizer into the tank without using a measuring cup. I now have one on all my bottles.

Fits perfectly and works flawlessly. Whether it will keep working well over a longer period remains to be seen. Recommended

I bought two of these dosing pumps in the intended combination with two 500 ml bottles from Aqua Rebell.

These dosing pumps are essential, since otherwise precise dosing straight from the bottle isn't possible. However, it's good that they can be ordered separately, since the pumps can be reused.

So you depend on the dosing pumps, but I found that the dosing pump doesn't fit the bottle. The plastic tube that goes into the container is too long. It's probably a one-size-fits-all part that can also be used for 1 l bottles. So I take the dosing pump out again, and the first bit of fertilizer already ends up on my desk. Then I measure the tube and cut it to size for my 500 ml bottle.

Once the right length is found, I screw the dosing pump onto the bottle. The valve of the pump is closed, though, which I already find unusual. In addition, there isn't enough empty volume in the bottle to make up for the volume of the pump. The pump displaces the contents of the bottle, and the next load of fertilizer ends up on my desk when screwing it on.

That must not happen with a pump that belongs to the bottle. There is a lot of room for improvement.

Good that you can simply turn the tap closed and open. The pump is somewhat longer than what you need for, e.g., the 500 ml bottle.

Great value for money, always happy to order again! It makes dosing considerably easier and is relatively accurate, but you should double-check to be safe!
With a small measuring cup or syringe.

With these dosing pumps you can cut the length off exactly as you need it. I hadn't known that at all, but I think it's great!

Works well, does what it's supposed to do. The tubing had to be shortened a bit, but that's no problem with regular scissors.

You can't go wrong with this.
Easy dosing, since each stroke gives 1 ml. Great for daily fertilizing.
Highly recommend. Greetings

Well, what is there to say about this pump 🤔. It fully serves its purpose and is super practical in combination with the estimative index!

Really nice gadget. Ordered it for my 500 ml fertilizer bottle from Aqua Rebell. Cut a few centimeters off the end, screw it on and pump :)

... the claim that it's 1 ml per pump stroke isn't quite right.
I bought 4 of these dosing pumps and all of them give ~1.2 ml - 1.3 ml

Easy handling for the perfect dose! No measuring cups that you have to rinse and find first. 5 more words to go, hee hee.

Great dosing pump. It could only be improved if the suction tube were a bit more flexible, then you wouldn't have to shorten it for the small bottles and it would "lie" on the bottom of the bottle, so you could get more of the leftovers out of the bottle. But that's complaining at a very high level :P !

If you can make your work easier, you should do it ! The dosing pump belongs at the very top of the must-have list. Daily fertilizing is done in no time .

Does what it's supposed to do, helps with quick dosing. The pump strokes are a bit jerky, but I'd still order it again.

This is a dosing pump, which can easily attached to any bottle with suitable dimensions. It does its job, but attention must be paid to the following details:

1) the tube has to be manually cut if used on a shorter bottle, as it is of the appropriate length to be used on a 1000 ml bottle
2) the pump actually doses about 1.2 ml of liquid, so about a 20% more of the nominal 1 ml
3) one out of four pumps I bought leaks a few drops of content from the base of the push-button.

So, I recommend to get this item only if you are aware of these almost-defects.

There is one limitation, though. With the complete iron fertilizer, the whole thing gums up over time. The first stroke may dispense a bit less, but that's not a problem, since the plant mass isn't the same every day either, or you just press a half stroke more. Delivery was lightning fast.

Maybe it would be good service to simply include the part for 1 € for free?
I find it a bit excessive to have to order something like this separately... but okay, 1 € isn't the end of the world

Simplest handling. The pumps are leak-proof, so you can shake and swirl the container without any problem. Fits the 1 l fertilizer bottles exactly.

the product has been very well packed and delivered good quality and worth for the money i have paid off

I've bought it three times by now for the different fertilizer bottles and am very satisfied with it.

It's always 1 ml per squirt and that makes it immensely easier to add the right amounts when fertilizing.

Practical dosing pump, simply screw it onto the bottles (shorten the suction tube if necessary) and off you go.

For small amounts in the milliliter range, a real help.

Measured it...it really does only dispense 1 ml per press.
So far I'm satisfied with all the products. . . . . . !

It's important, though, to make sure the length of the suction tube is adjusted to the corresponding bottle. I'd buy it again anytime.

All good, I like it a lot ... why do I have to write 20 words ? :D
Can't this be changed? :D

Fertilizing in fast-forward! No more measuring, no more accidents with disposable syringes, especially with little liquid in the bottle. Highly recommend :)

Very practical for larger tanks. For smaller ones, the new dripper attachment is better, though. For the 500 ml bottles, cut off the suction tube, pull it off and put it back on upside down, so the cut end has the notch again.

this dosing aid is absolutely good and fairly accurate. Good decision to order it along with the rest, because otherwise it would be a bit awkward to dose a few ml from the liter bottle.

Use these pumps for the aqua rebbel plants nutritions. Works great.
Quality is good and they are cheap.
One push is 1ml so you can dose on the ml.
If you have a a aquarium under the 40 or 50 L dont buy this product becouse most aqua rebell products are 1 ml pro 50 ore 40 L then you will overer dossage your tank.

It does what it's supposed to. Dosing works well, also suitable for large bottles. For my 500 ml fertilizer bottles the suction tube had to be shortened, then everything works flawlessly.

The new pumps are more precise than the old ones, where you often had to pump 3-5x until you finally got a full stroke. The old ones also tended to clog, especially with iron fertilizers. They can be locked by turning right and left, screwed onto any of the Aquasabi bottles and individually shortened. They can also be cleaned if it ever has to be.
You usually get a new dosing pump with a new liter bottle of fertilizer anyway, though. Top product for little money.

Well-made and above all sturdy dispenser. I really like that you can lock the dispenser. GREAT product. The accuracy is acceptable

It does what it's supposed to do - dispenses exactly without problems, the suction tube has to be shortened by a few cm before mounting, depending on the bottle.

When you press the pump head down, you notice that it doesn't glide down smoothly but rattles. These vibrations make the valve ball inside jump up and down. As a result, different volumes are dispensed.
Since the thin-walled plastic bottle is inevitably squeezed while pumping, the resulting overpressure causes more to be dispensed.

Over 20 pump strokes, a mean of 1.30 ml with a standard deviation of 11.5% was measured. The highest and lowest values were 0.55 ml apart.

If you put the bottle on the table and operate only the pump head, without squeezing the bottle, the values improve:

Mean 1.20 ml with 2.3% standard deviation. Difference between highest and lowest value 0.1 ml.

I'd be very happy with these values, but unfortunately I have to hold the bottle in my hand while dosing.

The problem could be reduced with a stable bottle (glass or similar).
Alternatively, a metal ball could be used instead of the light plastic ball.

For the price I don't expect a high-quality analytical instrument, but with this accuracy I might as well just eyeball a splash.

Every aquascaper should own one!! With the pump part, the fertilizer is very easy to handle. The bottles could be a bit nicer - the competition has realized that as an aquascaper you also like to show off what you use to care for your plants... ;-)

I have about 5 of them in use, and one of them always draws in some air, so you have to pump 1-2 times before anything comes out.
But at 1 €?! That doesn't bother me.

So, a good product.

Hello,
I ordered a dosing pump each for my 500 ml NPK and iron fertilizer bottles.
What I didn't like so much is that the dosing pumps apparently come in one size and are too long for the 500 ml bottles. Held up roughly and cut off, they fit then.
What is more serious for me personally is the fact that one stroke dispenses 1.15 ml and not 1 ml, which I measured several times with a medical syringe. With 12 strokes that would be almost 14 ml instead of 12 ml, which is an overdose.
Now that I know how much is actually dispensed, I use correspondingly fewer strokes and thus arrive at my approximate dosage.

My conclusion: The dosing pumps are practical to handle, but for accurate dosing I'll probably stick with my syringe.

Best regards
Marc Weaver

Useful for dosing fertiliser etc, they don't always produce the same amount of liquid per pump but still they are good for daily fertilisers.

Easy dosing. I use it for water conditioner and daily fertilizer. That way, especially for smaller tanks, you quickly get the right amount into the water. The screw cap fits normal bottles. Always label properly when decanting!

Since I fertilize daily in several tanks, a real relief. Only the first 1-2 pump strokes dispense relatively different amounts. In the 450 l tank I don't care. With the 30 l cube, e.g., I'd rather use a syringe. For the price, though, it's worth buying at the very least.

This is a very easy-to-use pump for dosing. The output is exactly as stated. Very good product.
And many thanks for the customer friendliness.

very sensible for dosing daily fertilizer, very convenient with "open" and "closed" positions
* * * * * * * * *

Very good product, dispenses exactly 1 ml. Aquasabi impresses every time, with every order, and the support is legendary, always very friendly and accommodating!

The dosing pump sits on my NPK fertilizer, so I fertilize exactly the right amount daily - without spilling or overdosing. Simply great little thing!

Very practical for manual daily fertilization, saves a lot of time. Saves you from drawing it up with a syringe or filling a measuring cup.

On my liquid fertilizer this pump is simply practical and makes daily dosing easier.
No more fiddling with a measuring cup. I think it's great.

Value for money is right, but I had to shorten the tubes on the 500 ml bottle, which I don't find bad though. Otherwise excellent

I like the new version even better than the previous one! :-)
A great thing that everyone should definitely have on their fertilizer bottles.

What is there to say...this dosing pump is great for fertilizing and you can add your fertilizer to the tank accurately by the 1 ml. Excellent!

The dosing pump works flawlessly and dispenses pretty much exactly 1 ml. Measured with a syringe. The dosing head is well made and has no sharp edges. It turns easily from "Stop" to "Open".

Dosing really doesn't get much easier. No need to measure or use a syringe . Just count the pumps and done 😂😜👍🏽

Very useful in combination with the empty plastic bottles! One stroke = 1 ml always fits exactly. Even if you only need the dosing pump once a month.

Hello,
This is my 2nd dosing pump now. The quality has improved again, and at a low price. An absolute must have.
Norman

The pump dosing makes working with the big 1 liter bottles considerably easier. Those are harder to dose otherwise.

Simple and good. What would be EVEN better: an adjustment option for different stroke lengths, so you can choose between 0.5 ml and 1 ml.

Hi,
I've been using AR for over two years.
The old "pumps" were okay, but not so accurate and sometimes clogged up.
The new version is different.
Easier to use, always accurate and doesn't clog up as quickly.
That earns it five stars!
Regards
Sebastian

Dosing not 100% accurate, but totally okay for the price. Also delivered insanely fast;). What more could you want :D

Luckily, when I ordered my Aqua Rebell fertilizer, I also decided right away on these matching dosing pumps - otherwise daily fertilizing probably wouldn't work. One stroke and done.
The question remains: why isn't the dosing aid included with the Aqua Rebell fertilizer products in the first place?!? Whatever, you can get over the price, recommended.

works flawlessly and doses the right amount, easy to handle, highly recommend and would buy again.

In itself the dosing pump does what it's supposed to. It's just not exactly 1 ml. But no big deal, since you dose by approximate figures anyway.

The 1 mL dosing pump is a big help with aquarium fertilization.
It is a bit stiff, but fits the fertilizer bottles wonderfully.

Perfect for dosing . Saves you the syringe :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-)

Finally no more messing around with a syringe or measuring cup. I use the Aqua-Rebell fertilizer series and it fits perfectly. There's an attachment for every bottle and the handling is child's play.

Simply highly recommended for daily use. You take the bottle out of the cabinet and press as many ml into the tank as you need. Simply great. "Must Have" for the Aquarebell fertilizer bottles

A tool that really needs no customer review. Simply essential for daily use. Buy it once, use it forever. Simple and very good.

I ordered three fertilizers from Aqua Rebell and a dosing pump for each bottle right away. Unfortunately, one of the dosing pumps only produces foam. The other two work great, though, and precise dosing is much faster and easier.

Highly recommend

What is there to review. It works. :-)

It's not always the same amount. It's enough to just not use it for a day. With daily use, however, no problems.

Great product. Finally no more pipette or syringe mess! From now on a dosing pump will be bought with every new fertilizer!

A great invention. Highly recommend.

Basically a good idea, but if you don't use it for two days, less comes out. Sometimes only half, and closing it every time is annoying too, since a pump stroke is lost that way.

Does what it's supposed to do ;)

Perfect and would buy again

Very, very practical !

I'm disappointed with the dosing pump. The price is okay, but you have to pull the pump head back up after every press. The dispensed amount also varies, on all three of my pumps and with every pumping stroke.
Suggestion
As an alternative, sell a dosing pump with a decent spring and a pre-chamber where you can also see the 1 ml.
Or, as I'm doing it now, a pipette with markings.
However, very fast shipping, DHL tracking by e-mail.
I'll recommend Aquasabi.

Very practical and cheap!

Great dosing pump. Fits exactly on the empty HDPE bottles offered here in the shop. The tubing can be easily cut to the bottle size with scissors.

The function is great. Very high-quality workmanship.

Does what it's supposed to do.................important, though, is to make sure the length of the suction tube is adjusted to the corresponding bottle. I'd buy it again anytime

The pump pumps as it should, but unfortunately the bottle (iron-sensitive) can't be shaken anymore. Point deducted.

Comment Aquasabi: Our fertilizers (Aqua Rebell) do NOT need to be shaken.

GREAT ! Lightning-fast shipping ! Highly recommended !

Super practical to use.

The pump offers easy handling with sufficiently accurate dosing.
Only the seal isn't always quite optimal, which is absolutely negligible, though, unless you want to turn the bottle upside down.

Extremely practical and quick to use!

Pretty good, but it could seal better.

You can dose great with it!

Perfect...!!!!!!!!!!! The easiest way to add fertilizer accurately.

Great thing!!!!!!!!!!

Works: Does what it's supposed to do - makes the daily fertilizer addition easier

Neutral review, since I haven't tested the product yet. But I was asked to review it.

Flawless, ideally suited for daily fertilizing

Dispenses with sufficient accuracy.

Good accessory! Makes adding fertilizer easy!

Very fast shipping, nice contact and GREAT product...what more could you want?

Super fast shipping, product works flawlessly

Yes, dosing pump-> You pump, it doses-> great!

Not quite 1 ml as promised , but it does its job .
Whether it's 00.1 ml more hardly matters .
Fast delivery !

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

Works flawlessly!

Great as always. A must for anyone who makes their own fertilizer.

Great - very practical and easy to handle!

Quite usable overall, but doesn't dispense the right amount of 1 ml, at least not with a single pump

Makes fertilizing immensely easier. Super tool.

A great little piece. Cleanly made, good material, fair price. The following points could be improved: for 500 ml bottles the riser tube is too long; a ring-shaped "500ml" marking would help to cut it at the right spot with a cutter, otherwise it kinks in a 500 ml bottle and the fertilizer intake is obstructed.

big help for little money for daily dosing

Good idea, this dosing pump.

A fairly accurate dosage of 1 ml. Every now and then the pump squirts uncontrollably and messily.

This dosing pump fits almost any bottle, a must for anyone who makes their own fertilizer solutions. The price is unbeatable too.

Dosing is unfortunately not always consistent, otherwise good.

Don't want to do without it anymore!

all good, would buy again

Serves its purpose :)

Excellent dosing!
Tubing can be shortened for different bottle heights, a big PLUS!

Really makes fertilizer dosing much easier.

easy dosing, for the daily fertilizer addition.

good, simple dosing aid at an unbeatably low price

Super easy to handle!

affordable and good ,
really excellent

The dosing pump is unbeatably cheap.

a must for the Aquasabi fertilizer bottles!

works without problems

works and is inexpensive, what more could you want?!

Simple, effective, good!

Very useful ! Indispensable for daily fertilization.

Sturdy dosing pump, fair price and fast delivery!

Hi,
the dosing pump works flawlessly.
Dispensing 1 ml per stroke makes dosing child's play.
Highly recommend

Simple and practical for dosing...

Very good product and very low price!

Just plain practical and very accurate

Great! Makes daily fertilizing immensely easier.

Good product. I buy it for every fertilizer bottle.

I find it very practical, since you don't have to fiddle around with unscrewing caps and syringes every day. I'd pick it again every time!

Easy dosing is possible with it, works very well for smaller amounts of fertilizer.
