i know everyone says to use paper towels. i am using lizard litter dessert blend(ground walnut shells). i was wondering if anyone has ever had any problems with this product. also if i do switch to paper towels how do i regulate the temp over the uth. now i have a good inch of the substrate to keep it from being over 90deg. i started with the wood shavings and it was getting close to 100 over the heater.
