Aquarium Advice Addict
I just got a sponge filter and need a quiet air pump to run it. I have a Fusian Quiet Flow I am using on a hospital tank right now but it is kinda noisy. Not as noisy as I remember from childhood but still a distraction. It sounds like insects humming in the distance. Just enough to annoy me. The sponge filter is going into a 5 gallon tank.
