had a thought about placing a rock in my tank for my bp to bask on. i am wondering if it would make sense to place the rock under the UV light thinking that the light would heat the rock up. same idea as a heat rock ( which is a no no ) but just something that would conduct heat and retian it so that my bp could lay on it. i am using UTH but only on my cool side, and i us a UV light on my hot side.
