Alright, so I have the plants in the tank and there is probably 3-4 inches of substrate. The problem I am having is heating the tank, there is a 150 watt heat lamp and a 100w CHE on the top of the tank, but at the substrate, the temperature is still only 75 degrees. Additionally, I can also feel the heat building up in the room so I know that its mostly just escaping the tank. I have some foil to insulate on the warm side of the tank. Any tips on how to keep the heat in? I am also going to add some plexiglass or something on top of the tank to keep humidity in.
