Heres my thoughts I would NEVER have to worry about a flood this way also I only really have to purchase one big ole pump that I plan on hiding with a rock pile in the corner. I do think once the canopy is completed its gonna look pretty nice loaded with plants up there ya know. This is going in my man cave so some speakers hidden within the plants for some tunes. I just picture it in my head looking really nice. I have access to major walmart discounts and free PVC piping so basically I have to buy a tank and a pump & thats about it. Hell even my lighting is gonna be free. The more money I have for the tank is my goal here.
