I already had the "medium" heat pad(designed for 10-20 gallon aquariums) and rheostat. An important note about these heat pads is the surface temperature is 115 degrees. I use a rheostat to dial it back down to 95 degrees.

Whats a rheostat and where do I get one. I have both my tubs on UTH's and i think it may be to hot.
