i have AC, but the outside temps are still making my chams tank raise 10 plus degrees. I am using a linear t5, a repti sun uvb dome and a 60wat heat bulb. normally this keeps her tank rght at 80. but this weeks been sitting at 90-95. can i just all together turn the heat bulb off? will this bother her? i guess i can go buy a 40w but im trying to avoid buying more lightbulbs if possible ty.
