I live in Massachusetts and we had a 24 hour blackout a few days ago. During this blackout, I grabbed an extension cord I was using to run my quarantine tank (it was empty; just live rock and sand) in the basement to run from our emergency generator to another part of the house and just remembered last night that my QT was still unplugged. The water temperature is 54 degrees right now. Did I kill all the beneficial bacteria? It was cold for about four days.
