well I have now learned that it is a good idea to either purchase a genrator or a battery powered outlet like what they offer at live aquaria.com. I just lost my entire contents of my salt water tank. I have been without power for two days now i went and rented a generater sat morning when my fish were still alive. but unfortunately the damage was already done. so those of you who dont have either a genrator or battery powered power source i suggest you get one. i now have to restock the $ 200.00 in fish i just lost. my homeowners ins doesnt cover it infortunately cause it was caused by mother nature. 70 mph winds ans two bigs trees narrowly missing mine and my neighbors houses. just wanted to pass this along.......Soon as i restock i will post new pics.......thanks cathy
