Hi guys! I just setup tubs for my ball pythons with Ultratherm heat mat. May I know what kind of styrofoam is good for being put under the heatmat? I find some in Walmart like this https://www.walmart.com/ip/Make-It-F...White/17422651. or https://www.walmart.com/ip/FloraCraf...Sheet/21685998 Are these kinds of styrofoam good for the heat mat? Or should I pay attention to the thickness or something of the styrofoam? So the reason we put styrofoam under the heat mat is to make the heat directly go inside the tub right? Actually currently when I use paper towel, the temperature is just perfect inside the tub. If I use reptichip coco, It seems the heatmat is even at more than 120F but the tub is still only 80F....May I know would the styrofoam help a lot for this? Thank you so much!
