I'm looking at acrylic coffee table aquariums (48x24x16) and I'm wondering if it could be heated from below the tank to avoid any wires running down the side of the tank. I was thinking of lighting it with a bunch of incandescent bulbs? would it be able to be controlled? any other way of heating it from below? Also what would be my options from filtering it by drilling the bottom? I'd like the keep the stand around 6" high. It would be nice to heat and filter with as little showing in the tank. If its not possible, I could live with a box in the center that I could hide with some fake plants or something. the bottom will be covered with marbles or glass beads. And if its not too much to ask, it would be nice to run the air pump lines through the bottom as well lol.
