The top plastic rim is scratched pretty good, so no open-top use, but a canopy will hide it, and it'll work great as a sump too. If nobody uses it, it's gonna the refugium for the upcoming 240G (I know it'll fit, I just know it!), hehe. Help me buy Shawn's 75G!UPDATE looks like I'm gonna get Shawn's tank for $50, so I cut the price on this item to $40... cheap tank for somebody, and I don't think I'll ever use it.
