Ok, assume I go with a heating pad.... how big of one do I get? What kind? Brand? I need a rheostat for heating, correct? To adjust the temp. Can I attach the uth & then cover it with linoleum or slate tile? What size wattage bulb then would I need for night time heat for a tank this size? Would a water hide be good for a water bowl? And a cool side with sphagnum moss hide?
