I have a 20 gallon long and on one end I have a uth and on the other end I have the heat lamp. I know that there is only supposed to be one warm side but what I do is turn off the light at night so the other side is still a source for heat for them. Would it be ok to leave the heat lamp on too or will that screw up their daynight cycle. Any comments? Also if you can please post your heating setup
