Quick question guys. As this says I just got a tub but now I'm realizing I'm having a hard time keeping the ambient temp above 71. I live in CO and my house is normally about 73-77 so the temp in my room isn't high enough to keep the ambient up. I have an extra uth from the tank I had her in. If I put that on the top (connected to the thermometer of course) would that help raise the temp? Would it do the same thing if I put it on the bottom?
