my new BP is housed ina rubbermaid tank with small holes drilled for ventilation and a sqaure wire mesh cut out on one side for the heat lamp. i keep my tank in my bathroom. my temp on the side with the heat lamp is within caresheet requirements, as is the temp on the cool side. the humidity level is also within caresheet requirements (probably due to showers and the fact that i have the heat lamp over the water bowl). SOOOO.....do i still need a UTH pad since all my levels are fine?
