Hi, I am new to the forum. We got a 150 gallon aquarium so my daughter's bearded dragon could have some more room to move around. I want to get it setup correctly before we move her in, and I am having some trouble getting the temperature up. Currently I have 2 ceramic heaters, a mercury vapor light, and 2 three foot fluorescent UV lights. One end of the take is at about 85 degrees and the other is at about 72. Any recommendation on how I can get the temperature up to a desirable level? I have heard bad things about heat rocks and under take heaters, so I could use some suggestions.
