Tank Crash thanks to a aqua heat titanium heater

[sitandwatch]

Running an aqua controller I checked the log and it looks like maybe an amp jump at a point but nothing else really stands out?

This morning corals are bleached, hammer is looking near the end only missing one fish now figure he is buried in the sand, toad stool is limp

Trying to get the tank temp up two 300watt heaters going right now
