Mini Air Pump

This actually IS really quiet and boy am I grateful. I have purchased two of these now for tanks located near my bedroom. The only sound is the fizzing of the bubbles. However, this comes in a small box (of course) and the air hose is tightly coiled. It has a memory and it is impossible to straighten it so that it stays where you want it and doesn’t spiral all over the place in the tank. I tried plant weights, which helped a little and clamping it to the rim at the top which helped a little. In the end I used a different piece of air hose that was straighter. The second thing is that the suction cup that comes with it doesn’t do a great job of holding the unit in place. This is partly because of the tension created by the stiffness and the end in the air hose at the top necessarily created by attaching the air hose to the unit. I ended up using a bigger suction cup left over from another project. Both problems are solvable and the silent running of the unit is worth it. Highly recommended.

Muy silenciosa y práctica para pequeños acuátios de Bettas. El acuario de mi Betta es de 10 lts y le funciona perfecto. Yo le cambié la piedra por un pequeño filtro de carbón activado y esponja. Funciona perfectamente y mi Betta y yo estamos muy felices.

works very well

Super quiet, all you hear are the bubbles. Works well with a small sponge filter I also got off Amazon.

I like this pump because the size is perfect fro my 3.5 gallon betta tank and it is so quiet. It has made betta a happier little fish too.
