Does having a fishless tank make anything easier? I'm trying to decide between a terrarium and planted tank. One advantage I like is no filter. I'm tired of crappy canisters and HOB's. I may eventually build my own canister, but I want to put that of for now. I know I need some water flow and figured I'd just get a koralia for that. Also do standard shoplights give enough light. I'm thinking about 4 40w T12's over a 75g.
