Came home yesterday from vacation to find that the power had been out for at least a few days. All fish dead, most of which I've had for 5+ years and one I've had for 13. Heartbreaking is an understatement and now I'm watching thousands of dollars of corals die in front of me. Trying ro save what I can but need some advise. Did a partial water change but just caused a bacteria bloom. Full water change? Move what I can? Or wait it out?
