Could use a big dolphine air pump, I have one that i bought from kensfish.com a while back, used it to drive sponge filters in 6 tanks, but it could have easily handled 10 or more. It has been running for close to 2 years with out a break and is still going strong!!! AND i believe i only paid like 18 bucks for it!
