I saw there is a lot of bad winter weather out there and Texas is even doing rolling black outs. I hope everyone's tanks stays safe. We had some snow and ice here in the Portland area with about 200,000 without power. We lost power for about 4 hours yesterday but thanks to watching the BRS video a couple years ago about back up battery power which made me purchase one to keep my power head going, my tank came out ok. I did put a blanket around it and my 75 gallon tank only lost couple degrees before the power came back on.
