Danner Manufacturing, Inc. Supreme Hydro Oxy-Flo, AP-2 Low Volume Air Pump, 1.5-watt, 40512

I bought this pump for a sponge filter in my ten gallon planted I expected to be the bare minimum to run it, but this pump is more than I thought in every way, I had to put a simple bread tie in the airline to restrict some flow to it I love it.As for noise if it's mounted on the wall it creates very little noise besides the expected small hmmm sound but it's not too loud if it's just sitting I wouldn't put it too close the fish tank though.This pump is worth the money would recommend

Seems to be consistent and reliable after a short time so far. Sleek design and reasonably quiet. There is a slight hub and vibration but blends into any kind of ambient noise. UL approval is key for safety certification and design since it's electrical. Priced at clearance level, but full retail value and quality.

This is my second one and they are the quietest air pump I've ever used

I bought the 1.5 watt and attached it to a 4 or 5 inch bubble wand. It is just right for that setup and is a little quieter than the bubbles breaking on the surface of the water.

Quite not a lot of pressure if you were tryna go cheap with big results.. not happening. Does it’s job tho..

Consistent power for a few months now. Definitely recommend

Very quiet!

It worked, albeit minimally and inconsistently, for the first two weeks in a 20 gallon tank. After that it didn't have the strength to move any air whatsoever if the air stone was submerged more than 3-4 inches. After a month it doesn't move any air at all, even though you can hear and feel the motor running. More than a complete waste of money; it's an aggravation to be stuck without an air pump while I find something new.
