my buddy manny gave me a powerhead and I've seen it on ebay plenty as aquaball. But I don't have anything else that comes with it so I never really used it. I threw this togethor real quick, was going to paint the white part black krylon. Where should I drill holes in it at?? Or just cut the bottom off clean?? What type of media??
I was going to cut the bottom flat and put a circle piece of foam in it and the rest bio balls and call it a day. Or I can drill wholes in the whole thing and do something similar.
Thoughts anyone?
