Temperature problems

[NYHC4LIFE8899]

You're not as confused as I am, lol. I pulled out the probe thermometer and will use the temp gun instead :-)

The towel is on top of the foil just for extra weight to hold the foil down securely.....another layer of insulation.... P.

Oh ok,lol,I gotcha.good thinking
I keep my probe thermometer in the tank right above the center of the UTH to make sure my heat mat is working properly. I very rarely use my temp gun..I also have a hydrofarm thermostat regulating the UTH
