I'm so confused, if your not suppose to use a heat lamp for heat then how are you suppose to keep the tank warm? Right now I'm using a 75 watt bulb on 20 gallon long tank. My hot side is saying 96 degrees with the heat lamp. I haven't bought my first BP yet, just testing things out. Now 1 is that too hot and am I suppose to use a heat lamp at all? Also when I cut the heat lamp off I notice the humidity goes from 47% to 75% in the tank. OVERALL IM CONFUSED WITH THIS TEMPERATURE THING, PLEASE HELLLLLLP
