Good morning I've had about 150 pounds of dry Rock cycling waiting for my fish tank to arrive I had an old heater in there that stopped working and the tank temp got down to about 70 degrees my question is did I kill the bacteria I'm about six weeks into the process and would hate to think I would have to start over because all the bacteria dies because the water got too cold or will it be fine
