I'm so sorry if these post are getting annoying. I just spent the last couple of days messing with my tank and trying to fix my temperature issues. My tan currently sits at 83 ambient air and 77 under the tank on my cool side. It is 94 under the tank and 78 ambient air. Are these ok? I have my CHE on my cool side. Its only 100 watts would a 150 watt bulb help?
