I don't want to be a dick, but the person asking the question specifically asked; " If you use an aquarium air pump, which one do you use (Brand) and what size ( what gallon tank rating)?? "
Most replies DID NOT SPECIFY MAKE OR MODEL. The reason I'm getting my panties all in a twist is that I have the same issue. I just bought a $37 aquarium pump for a 100 gallon tank, a "Tetra" brand, UPC 0 4679877855 4. It's totally useless. It's got two outputs which I hooked together using a T, with the single directed output to the saw. USELESS! That's why people ask specific questions. Very frustrating.
