This has happened to me a couple of times... even earlier this week when the heater in my small tank died.

Low temp for short periods isn't bad... as long as it happens slowly. Same with bringing the temp back up. As long as you're going slow, it should be fine.

Anyone know if the ocean stays a constant 78C?

I wonder... does anyone care enough to read signatures if you make them really small? I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.

I know my response is too late to be of any help...

18C or 64F is very cold. If temperatures stay above 70F there isn't usually any trouble. Even though the temperature wasn't that cold for that long, I would still be very concerned. I would be trying to warm the tank up to 70F as quickly as possible.

If there is mature macroalgae in the tank even relatively small temperature swings (both down and up) will often trigger a sexual response. Be ready to do some big waterchanges if that's the case.

Everything lived the night but I have some very unhappy coral and one of the chromis is pretty sluggish but the tank is near normal temp now. Might lose the chromis but everything else should be fine

While in Europe for 2 weeks (in Sept) the power at my house went out and I lost my Flame Angel. Power was out for +/- 6 hours. My temp went down to 72, I hate these issues while you are on the other side of the planet.

Power came back on and my Apex and Osmolator all came back on-line perfectly and corrected everything. Its great to have the Apex, it emails you (once its got power again) letting you know the out of boundary params every 20 minutes & you can watch it work. The graph after was also neat to see.

I just hate equipment failures.

Might need a battery backup.... to run a pump and heater....
