Thanks I am all over it Last night I ran them all night and forgot my heater wasn't plugged in any more, well this morning my temp was 74ish from last nights 80ish. Heater is on an so are the light, hopefully that was the only huge swing in temp I will have and hopefully everyone in the tank just thinks an overnight cold front blew through.
