I have my 2500g female in a 55g tank right now until we get the 41q rack we're having built because I don't want to keep her in our 28q. I'm using aspen bedding & flexwatt on a dimmer to heat it. My problem is, she's so heavy that when she moves around, she just bulldozes all the bedding and ends up directly on the glass. I have it steadily at 91 degrees on the bottom glass at the hot side, but on top of the aspen (which is a thin layer on the hot side so the heat can move through easier) it's only at 74, with an ambient temp of 78. Any suggestions on how to bump up her temps without the risk of burning her?
