AQQA Air Pump for Aquarium Adjustable Aerator Pump 2 Outlets Fish Tank Air Pump Ultra-Quiet Oxygen Pump for Hydroponics Freshwater and Marine Water Tank (5W for Up to 80 Gal Tank)

Probably the best air pump I’ve bought to date. Better than the aqueon whisper pumps by far. The dual line is nice. The adjustable airbflow is even better. It’s quiet. It is big. 12oz can in photo for comparison. I’ll definitely buy again and for my other tanks.

The media could not be loaded. I really like this pump. It's quiet and has great output.

Great prod. Keeps tank clean

This pump is great I use it for a underwater sponge filter. This pump is super quite it half the time I don't realize it is on unless I'm looking inside the tank and seeing the bubbles! The only thing I will say I wish it had is an adjustment because it states it can work up to a 40 gallon tank. I have a smaller 6 gallon for our betta but he honestly loves it and has been more active after switching to the pump and the new filter!!

Good quality power and quiet

This product is mis-advertised on Amazon's website. The specifications state that it can deliver air to a water depth of five feet, but the instructions state that the maximum depth is 2.6 feet. I could not get it to deliver air to a depth of more than 18". My aquarium is 4 ft. deep so this air pump is useless. I will have to return it.

This pump is very quiet! The little suction cup feet don’t stick to the glass very well for me, but that doesn’t matter as it can sit next to the tank and you can’t hear it! It’s the quietest air pump I have ever had. So far it’s been about a week and working well!

Maybe I just got a bad pump but it is certainly not powerful. I bought this for a quiet pump to run a sponge filter (with air stone) in a 20 gallon long aquarium. Well I am very disappointed in it performance, it is extremely quiet but it pumps barely any air, certainly not enough to run a sponge filter. It will be going back.

De la puissance, de l'efficacité et tout ça sans bruit vraiment super

5 estrellas! completamente recomendada, silenciosa, más de 1 año de uso sin problemas de ningun tipo. buena potencia y calidad.

Can't even hear the pump running, all I hear is the bubbles off the filter. Probably the best purchase I've made for my aquarium.As long as it lasts ill buy more for my others!!!
