thanks, its wouldn't rock with me on it and trying to force it. it has about 85 screws or 1 box of them. im hoping to plywood it tonight. it took me about 4 hours and i didn't get done till about 10pm. Im hoping it holds well with about a 80g tank on top and a 55g on the bottome(in the future, right now its going to be a 20g.
