faulty heater?

LOL, no worries. I never believe what the heater says, I always have another thermometer and go by that. Once you hit your target temp, turn the heater down till the light goes off and keep an eye on it.

I hear ya but one glass thermo says 80 the second reads 76 one bought today an the first
is a month old, the heater is turned off right now but it did read 80 as well, so do i assume the second thermo that i got today is correct?

LOL, I dunno what to tell you, chuck one of the thermometers and go with the one you keep

Hahaha, i did figure it out with the help of two more thermos and an infared,
the old thermo was out by 5 degrees so over the course of one day the tank went
from 74-86. Now i just gotta me a better thermo than this $3 mercury one.
Do you use digital, pinpoint, mercury?
Lucky all livestock are ok but it must have been a trip for them.
