Hey guys, i was just at a garage sale and they had a never opened penguin 330 bio wheel power filter for $10, yet i only had $5 on me, so the guy just offered to give it to me for 5 to get rid of it. sounds like a STEAL to me.
it's obviously an older model, but it's probably similiar to the 350, just the older versionl? it says 330 gph, so how would i calculate how big of a tank it could handle?
