Holy cow, big +1 on what a ride, I swear I felt sweats come over me whenever you had issues and was on the edge of my seat hoping that everything came back to life.
That said, a decade ago
you mentioned you kept corals outside and grew them, how was the electricity to keep that going like that? I know you said it was warm, but still it had to have an effect. Also did you have large algae issues as well? I'm a little north of you (300+ miles) but I have a greenhouse off the back although the temperatures go from 50 to 110F in any given time period I always thought having a small 20-40g coral grow out flat hooked up to a 500g system would still work out.
