I've had my bp for a month now and I've had the heat mat for maybe a week longer than the snake. The mat died today! It was an ExoTerra Desert mat Large.I have/had it on a 29 gal glass tank. Has anyone else had these die after only a month of use?? I recently put it on an appliance dimmer, could that have done it?? My temps right now w/out mat on hotside are 85 and cool side about 78, heated above by a 100W red bulb. Do I need to buy another heat mat or can I just keep it this way? If I do need to get another heat mat could someone suggest one that works better and I'll be off tonight/tomorrow to get one!!thanks in advance!
