Thanks gr33n. I can't believe I have never seen one of those air distributors before, when I say I use to do large aquariums, I had a 280gal, a 170gal, a 75gal, a 55gal, and a 35gal, all going at the same time in the same room, I still got so many air pumps AND small water pumps out the whazoo, I bet I got 10-12 of those little Rio water pumps like came (or use to) in the SH, I don't know if they still use that Rio pump or not but you have to have alot of those small water pumps in a reef tank, I think if I get me some buckets, I probally got the rest laying around the house. Thanks again.
