Air Pump Running But No Bubbles – How to Fix this?
Air pump not working right... I'm having a frustrating air pump problem. I have a whisper 400 air pump that works fine when the air hose is at the top of the tank but as soon as whatever it is connected to is lowered to the bottom it quits about half way down. (It's only a 10 gallon tank so shouldn't be too deep for it.)Get Price
