ACEONE Manual Fish Tank Water Changer Aquarium Dropper, 2Pcs 30ml Aquarium Clean Pipette Dropper, Fish Tank Cleaning Waste Remover, Aquarium Gravel Cleaning Straw

In the best way possible. Helped me clean out fungus in my 10 gal tank in minutes with accuracy and precision. Comes apart for easy cleaning and seems like it should hold up over time. Not much else I could say.

Used these as sauce basters. When using with water, it does have a tendency to leak even with full suction but it worked for my purposes.

I use one for removing water from my tank and the other one for adding RO water so as to avoid cross-contaminating my RO water. They work great for moving up to 30 ml of water at at time. I keep invertebrates (shrimp) that are very sensitive to dramatic water changes so the 30 ml is the perfect size for my slow water changes. It also allows me to selectively clean the substrate without endangering the shrimp like a standard gravel vac would. Really handy tools. I use them all the time and they work wonderfully. In my opinion, they are a "must have" for shrimp keeping.

I bought this for my garden. It was a little too slow for me. I guess if I was using it for a fish tank it might work

These are great for getting water samples and filling up the test tubes. My only complaint is that I wish they were a little more precise. I sometimes get a bit more water into the tube than I intend.

I use these to suction axolotl poop out of the tank (gross) and I really was set in my choice being a no drip one due to what would be dripping out of these suckers.... unfortunately, these are not no drip. Although, they do suck the poop right on up I have to promptly get it upside down out of the water facing up to prevent it from dripping back into the tank, or even worse on me - BARF! They do the job but only a few stars from me due to the lacking no drip feature it said it had.

Very good suction, large capacity, the straw and soft rubber part can be disassembled, easy to clean, but the sealing is not very good, the liquid sucked up will drip out.

I have a 1.5 gallon tank for a betta. After researching and seeing good reviews for this product, I gave it a try. It is much better than the hose-type aquarium cleaner for such a small aquarium, but it really doesn’t clean the old food on the bottom of the rank very well, either. I think I am going to have to get a larger tank to solve the cleaning and heating issues I am having with this tiny tank.

Good product

No me convence, será práctico para peceras tipo balón pero para las de urnas es demasiado pequeño para hacer un cambio de agua con esto.

Es perfecto para acuarios pequeños donde limpiar con un sifón se hace un imposible.... tengo muchas rocas y plantas y por más que limpiaba nunca era suficiente... la verdad que este aparatito que desconocía en los acuarios, me ha sorprendido para bien . Recomendable 100%

Útil para limpiar pecera

Leider sind die Pipetten nicht Chemikalien fest, ich wollte Spritzusatz damit dosieren, aber nach drei Anwendungen war das Kunststoff komplett gesprungen und sehr porös.Fürs Aquarium bestimmt eine gute Sache, aber das war es dann auch, das Produkt darf auf keinen Fall in Berührung mit anderen Stoffen außer Wasser kommen.Hätte auch gerne etwas mehr bezahlt, wenn ich dann was aus Glas bekommen hat, hier wurde der billigste Kunststoff verarbeitet, den man gefunden hat.
