My heater went out in the off position. I noticed This when at work at 9am when I was sent an alarm from my Apex of low temp. By the time I was able to get home and replace it was 8 hours later and tank tamp dropped to 72.5 at its lowest point. 7 of my Sps coral look like they lost a lot of their pop { browned out } and my gonines were all retracted . Fish seamed lethargic and lost my favorite fish a 7 year old Hawaiian Cleaner wrasse and one Purple Queens.
Will my Corals recover?
