Ok so I was using a dimmer switch but just got a thermostat. Here is my question and a lil info on my set-up..
I have a piece of 12x12 tile laying in my tank over the UTH (distribute heat better). I then have aspen as substrate over the tile.
Right now the aspen is reading 82-84f. The tile is reading 94-96.
I do not have a thick layer of aspen and the other day i noticed that he moved the aspen and was laying directly on the tile on part of his body. I think it was his belly while was digesting. So my question is, do I keep the tile temp where it is and not worry about the aspen so much? I mean if he is laying on the aspen wouldnt it compact it and allow for the aspen to heat up more? Or do I try and get the top of hte aspen to 88f, but then if i do that i risk him moving the aspen around and laying directly on the tile and possibly burning himself!!?? Everything was perfect before i swithced to the thermostat and now its all messed up!! Errrrr!!
