I use a dimmer for my heat pad (have a thermostat in the mail as we speak for my rack system though...) and you have to point the gun directly on the glass where the mat is, also do it over the substrate. It sounds like it may be getting too hot, that's the problem I had that I didn't even know was a problem until I got my temp gun. I have a heat pad MADE for a 10-20 gallon tank, and the dimmer is turned down about halfway....they get very hot especially when left on all the time. Dimmers are about 10 bucks at Home Depot, you just plug it in and turn it down.
tank you for that response i got the home depot dimmer and now hes back to normal
