Okay here is my concerns, I have a 30x12reptile aquarium with a screen top. i have a heat pad that is rated for a 20-30 gallon tank. It did get cold over night and when i got up in the morning my tempature gauge that was over the warm side, an inch from the top and on the back wall,was at 70. The other side was 68. When i arrived at home, the warm side was 85 and when I picked him up he was comfortable warm.
It is making me think that I need to get into PVC cages and get a Spyder Robotics thermostats. Also what is the lighting situations.if i get the white fluorescent light, do i need a heat lamp.do i leave the heating up to the heating pad? How is the 11 inch flexwatt heat pad?
I think I am interested in the T3.
I would like to get other peoples opinions and information before I make take this path.

Thank yall for any and all information given.
