I would like to remove the river rock from my tank, and go bare bottom. I know I can remove the gravel without having to empty the tank, but I would like to have the bottom of the tank black. I would like to do so without having to empty it out to paint the bottom. I was thinking that I could get a piece of abs plastic, or pvc sheet similar to what arl used in his plywood tank. Just cut it to the correct inner dimensions of the tank, remove river rock, and replace with the abs/pvc so that way its "bare bottom" and black without moving or emptying the tank. Sounds like a doable idea?
