I have a reptisun bulb, a 100 watt incandescent bulb and an uth and my tank isn't getting warm enough. HELP! I think this is why Gwen is not pooping!! The incandest light fixture is 10" from the floor. I have to get something she can climb up on, as she had MBD, and what I had, she fell and got stuck, so I took it out. What should I use and how close to the lamp should she be getting. (I ordered the digital therm that is said on here to get, but in the meantime was just using regular therms and it is only showing 80 degrees under the lamp, on the floor. What will be safe for her to climb on to bask or do I need a stronger bulb???
