My mercury vapor heat bulb cannot get the basking section of my bts's terrarium over 90 degrees, heck, it can barely manage 85 degrees. Should I buy a ceramic heat bulb or is there a mercury vapor heat bulb that can get the basking section over 90 degrees? Keep in mind that the bulb would be about 2 feet above the ground and that it cannot be moved closer. I also added a heat pad for a 20 gallon tank for added temperature but it has not worked so far.
Any tips? I'm at my wit's end.
P.S, I am looking for a good brand for a mercury vapor heat bulb. I previously used the one from Lucky Herps but is there a more reliable brand out there?
