I have the air pump located in an insulated closet hanging from the ceiling to help quiet it down. Its an ActiveAqua AAPA70L that came with the tank when I bought it used. I'm running about 8 outlets off it on four different tanks. I'm going to try adding a Cobalt egg rocker to it tonight. First time using a tumbler and first time trying to strip eggs. I have a female Stuartgranti Maleri peacock holding now.
