I attached two bamboo stakes to either end of a "flower flat" tray to make a planter for my 20 gallon. It's basically a long, low black plastic basket that annual flowers are sold in. I just set the basket in the tank and it is supported by the bamboo stakes and I put plants (syngonium, philodendron, peace lily, pothos) in the little openings of the plastic. Look great, plants do well with their roots in open water and their leaves in the air, only problem is the basket does take up the entire tank. But wouldn't in a larger system.
