I bought a zoo med for my one tank. It was about 35 bucks. It can do 2 uth but you need to look at the rating of the stat and uth. Mine can run 2 but I only have one cause I finished my rack and am using a herp 4. I would use it for my tank as well but I had it before my rack. The zoo med is like a rheostat. Make sure you have a way of checking temp after you turn it on. Start on low and go from there.
