I think I have to call Mr.Dickey again and get a new thermometer. I have 6 in there and that one is way off.
Acu rite-97.6 + 99
coralife-97.1
came with thermo.-100.0
acu rite-97
flukers-97.7
acu rite-97 + 97.3
Should I get a new one?
I've never put another thermometer in there other than the one that it came with. Mine must be working fine, because I've had a couple of good hatches so far. I never really thought to put another thermometer in with it.
