RHETORICx said:sometimes i have issues keeping the heat up in the winter. i have to put a ceramic heat emitter on my beardies tank in addition to his mvb bulb. i think the heat emitters are pretty cheap, they don't produce any extra light (you could leave it on at night if need be). mine throws off a ton of heat.
where is the tank located? if its by windows or doors thats also going to bring the over all temp down.
