Would a pond/fountain pump work as well? I work at Lowe's so I could probably get one of those for a pretty good price. What exactly is an air stone, by the way? What purpose does it serve and how would I go about buying/making one?ColdSmoke said:
There's a debate about the pump size. I use a Top FIn Air-3000 rated for 40 gallon aquairums and works just fine http://www.ecrater.com/p/17419579/top-fin-air-3000-aquarium-fish
Yes, you do need an air stone or something of the sort. There are some folks around here who have made home made contraptions, but I just go with the air stones since they cost under $2.
