sorry ok here are a few pics. My tank has two heaters. one on the day side(right which comes on at night) and one on the night side(which comes on during the day. both my night and day are on the zoomed digital timer. I have the day come on from 6am-6pm and thus the night come on from 6pm-6am. The day temps range from 90-95. the night stays around 80-85. I have a water dish in the middle and a hide rock on night side and a little hide thing on the day side.
