I have the t stat probe in between the the tank and heat pad and another probe from an accurite thermometer directly on the glass the heat pad is heating. The accurite probe reads 95 but when I take the temperature of the substrate it's 83-84. These dam chips absorb heat like crazy. Would a plastic cage instead of a glass one absorb more heat somehow? Thinking about switching over to Sani chips if this doesn't work out.

Sorry about the late response, thanks for yours.
