Here are my plans. Suggestions are welcome! I plan on ordering the Laguna 2400 Maxflo pump to power this whole deal. Basically hook it up inline and T off at the top of the pump to distribute water to two boxes. Simple, water drains through Mech, Over Bio and back down into the tank. The only thing stopping me from this project is hearing back from Laguna to see if you can hook them up inline. I havnt found much on that. Also how to keep it up there. I the flower pots are thin so I can still have MY LED lights behind my glass hinges for opening and closing. I may run 2X4s across the top and make a platform to hold all this. Intake and returns could just be drilled through the wood supports. Pump will sit in the middle. Will also take suggestions on what size PVC to use and where to order some nice looking strainers for my intakes. Thanks. I want this to look really nice as well as be completely functional.
