I was checking the hot side of my tank and the temp says its around 94, but it feels cold. Is there a way to trap heat on the bottom of the tank? I have 2 UTH's and 1 heat lamp to (try to) maintain ambient air temps. I also use insulation on the outside of my tank, but the stuff I have it sticking to is velcro and I don't think thats good enough since its not pressed tightly against the sides of the tank and air still moves in the cracks.
