What are your temps and humidity.. Only time my bp destroyed his tank was when I was running a unregulated uth and he was to warm... But he was still eating..
Cold 78-83
Hot 83-86
UTH Thermostat set to 90 and gets tank only up to about 92 and thats below two laters of paper towel.
I have a gas furnace for heating so it gets cold and then extremely hot so thats why my temps change so much.
