COOLBABY Ultra Silent High Out Energy Efficient Aquarium Air Pump Fish Tank Oxygen AirPump With 2 Air stone/2M Silicone Tube

Very good product

I like it coz it has two holes don't like it because it makes a loud noise. And the rubber pipe quality which comes with it is very very poor.

I purchased this air pump expecting reliable performance, but unfortunately, it has been a very disappointing experience. While the pump itself seemed fine at first, the included air stones were of extremely poor quality. Within a day of placing them in my aquarium, they started to disintegrate and turn into a muddy mess.This not only made the water cloudy but also compromised the health and cleanliness of my tank. I had to do an emergency water change and remove the air stones to prevent further damage to my fish and filtration system.I would not recommend this product unless the manufacturer improves the quality of the accessories—especially the air stones. Not worth the hassle or risk to your aquarium.

I’ll give 2 stars: it works and strong but too loud - i feel the fish are disturbed too with the noise it gives, except the oxygen.—————————————I’ll have to correct my previous review. The device is actually silent depending on the location of your aquarium.

Noisy

could be a little more silent, but good flow,

Good motor for your fish tank.. its hot once touch it but good part is it gives very less noice , no disturbance while sleeping.. bcs my fish tank is next to my bed .. last week I bought this item.. until now im satisfied…

It does its job for my 5 gallon tank. Not very strong for big sponge filters, but enough to create bubbles in one end and push some water into my small sponge filter in another end.
