Hi, I've been setting up a tank for a High Red Ornate Pacman Frog. Everything is coming through nicely except for the whole heat situation. I have a Zoomed 10-20 gallon UTH and I have a Zilla 500 watt temperature controller and the controller is not working at all. Whether I have the controller set to 70 or 80+ the temperature in the tank tops 90+. Any help would be highly appreciated!!
