I had a outage in Brooklyn the week before the major one in manhatan it only affected a small area never made it on the news , I Am assuming it was off for 6 to 8 hours before I got home from work and when I arrived it remained off for another two hours . I walked in to all my medium sized fish , powder blue tang , marine betta etc already expired , then more passed my flame angel kole tang . In regards to coral 90 percent of my somewhat beginner sps was dead pure white others like shortcakes and such looked rough and expired the next day all my expensive frags looked terrible my crazy t , beach bum , kung pao looked real rough as well as Miami hurricane , reverse superman etc my bubble corals all dies with 72 hours from the aftershock so being conservative I'd say within 8 hours I lost four thousand in fish and coral ,, my attempt for a solution is a honda gas generator as a start and I'd like advice on never letting this happen again
