Thank you guys! I got the heat mat cause I can't seem to get the tank warm enough and I know that 80 is the temp I keep seeing over and over again so I trying to keep it close to that. If I am having that much trouble in the little tank then the big one I ordered is probably going to be a bit harder I'm guessing. The mat will be my back up plan. Humidity I either get it right on or a bit high. Darn Kansas humidity!
