I was upgrading my 55G FOWLR to a 75G. So I moved all my rock and fish into a large Trash can I use for water stroage, drop in a powerhead and heater. I then turn on the RO to let the new tank fill up and go to bed, today I walk down stairs to see how the salt is mixing in the new tank, when I feel a source of heat. To my surprise its the trash can, I take the top off and it is literally steaming off the charts past 110 where my thermometer will read. Complete loss fish and Live rock now dead.
