I'm heading to a reptile show this Saturday to hopefully bring home a new buddy, and I'm trying to set everything up beforehand so I know everything will work well. The only thing I'm really concerned with is the heating/humidity. I have a 40 gal. tank that I'm heating with a ZooMed ReptiTherm under-tank heater as well as ZooMed 75-watt basking spot lamp and nocturnal infrared heat lamp that I'm putting in 5.5" clamp lamps. I got reptile thermometers and humidity readers that stick to the tank and so far it reads about 30% humidity and about 70F temperature-wise. (I'm also using fir bark as bedding, I don't know if this affects temperatures or anything.)

Will it be too hot to leave both the infrared light and the ReptiTherm heater on at the same time, or should I turn one off for a certain amount of time since it's 70F in my house already and I'll have that basking lamp on as well? Or is having both heaters just overkill? Also I've read a lot of things over the net but none really say for sure how high/low the humidity should be. 30% seems to be the common but I'd like to know for sure. I'm trying to make sure I have most (if not all!) of my questions out of the way so I'm not crossing my fingers that things just work.


Thanks so much!!
