I was at walmart and there by the airstones they had a thing that looked like it was a rod made of airstone. Anyways it said it circulated the water better, I think it could probably just be suction cuped to the side of a 5 gallon bucket. Anybody done it, know what I mean? like would it make it like a whirl pool? IS WHIRL POOL WEED OK? wEED AND jAMeSoN tonight
