I've had my Ball for a couple months now. In the winter I had no problems controling the temp & humidity of the 40 gallon tank. With warmer weather the digtal therm recorded temp at 102. I know very BAD! But without being home to check every day How do I adjust the under the tank heaters. I have 2 of them, each one under a hide on opposite sides- cool area in middle. I also have a light. If I cut of one heater the other still produces high heat on a warm day. I went to Lowe's to look for some type of Dimmer to plug into with no luck. Help Please Thanks Mitch
