Hey Guys! I have a big question. I just setup up my new red eyed tree frog tank and I have an All water base that slops up to a patch of land. The water is about 3 inch. deep . So I wanted to know if I use a heating pad will it crack the glass????I have heard it before but is it really true. I using the exo terra compact top and I only have one Reptiglo 2.0. I know that they dont give off much heat. I was wondering if I should get the Reptiglo 5.0 or the Reptiglo 10.0 to increase the temperature? THANKS!
