As for the details of what happened..........I know what, just not how. I took my controller offline to send it in for repairs, so my ordinary set of backups were not there, but I have the heater and chiller connected to a Ranco 2 stage temp controller. When I checked it, the temp was up to 90 degrees. Delving further into it, the heat setting was at 220.:eek1: Chiller setting was set as a second heater and not coming on.
Now, only a couple of possibilities seem to be available.
1) My nephew got ahold of the controller and started playing. Not reasonable because of where the controller was located and how long he'd have to have been "playing" with it to get to the settings where they were.
2) A power outage nearly a week ago reset the controller. While the most likely scenario, it doesn't seem to make sense that I would not have seen a change in the tank before this morning. Like I said, everything looked great last night, not so well this morning. Still the most likely, and the corals were likely able to handle the higher than normal temps until this morning.
3) Someone really doesn't like me.
