I have a reptisun 10.0 UVB coil light in a dome lamp on the cool side, ZooMed 150W basking spot light in the basking area....it is a 30 gal tank and its about 100-110 degrees in the tank under the basking area and in the high 80's on the cool side of the tank...is this too much light and should I turn one off at night time or do they both stay on all the time....i'm afraid if i turn one off for like "bed time" that it'll get too cold in there by the morning? what should I do?
