My Tank crash - Hopefully you can learn from my experience :(

[Bblinks]

We had a 48 hours power outage and my tank was out of power for 12 hours before I put the pumps back on, unfortunately I can only run the pumps and the water temp dropped to 21 degrees and everthing still made it through....not sure if ammonia would set in that just 3-4 hours. It just doesn't make sense....even all my Sps pulled through and I have a lot of Sps with abandonce of fish. Obviously what happened to ops tank is heartbreaking and I feel bad for her but this is the hobby we have chosen, never said it was gonna be easy. Brush it off and start again, it's kinda fun to restock anyways, probably a good time to have a backup plan too....🙊
