power outage killing 2 months later?

Do you think a power outage could kill stuff 2 months later?

I had a 3 day power outage over 2 months ago. I had battery powered air pumps going 24/7, and was able to borrow a generator off and on (had to share it) that I used to run the whole tank. But the tank tamp still dipped into the 50s. I lost 1 fish, and a few corals that week, then it settled down. But I feel like it never looked 100% since.

This week, 34 heads of my hammer colony and a blue tort acro have died. 2 encrusting sps (idk what they are) are receding, and a lot of my other euphyllias look droopy. I've tested the water, I can't find anything wrong.

Do you have sand? If so there was probably a lot of die off within the sandbed. My suggestion would be to start aggressively cleaning the sand.

No sand, bare bottom. 125g display, 55g sump. I do a 30g water change once per week. High powered refugium keeps nitrates near 0 (I had to back off the rafugium light duration to keep a trace of nitrate).

It is possible. If nothing else stands out, then this is likely your huckleberry.
