power outages are a whole different world. Every Reefer should have a generator no matter how small your tank is. For me having the amount of money in my system it’s not even a question, I’d spend $1,200 all day long on a 10,000 watt Generac, then lose $300-$1,000 dollar frags and colony’s, You gotta be prepared for tank emergencies. Extra lights, pumps, salt, test kits and regents and back up tests, I always keep some icp tests on hand. You’d be amazing at the amount of people who are not prepared in the hobby.
