You need to get a blower. Most online stores carry them and have their specs. Your lfs can get them too, but unless they use one themselves, they probably won't be much help in terms of advice. When you think you have figured out which one you want, call the manufacturer to check to see that it is the quietest one. Some blowers can be extremely loud.

I agree. You need a blower or a larger linear piston air pump. If you aren't worried about a little noise, I have a Coralife SL-65 is a decent pump.
