I have a 26.5 gallon tank set up with the original lighted lid that came with it and have a small tri-leg high velocity fan on top with direction into the tank. Mine is simple, as a 1/2 dozen or so mounts hang from the top as well as small seedlings scattered about the bottom. The bottom of my tank has aliflor medium size pebbles to retain moisture. I water 2 times a day, and fill the tank up 2 times a week with tap water. Hopefully someone will chime in on a different set up...options are plentiful.

Glad you found the OB...a great place to hangout and learn about our addiction
