I was one of the unfortunate people to go without power in Charlotte, NC for 5 days after the ice storm 2 weeks ago. I was able to keep things alive in my 90 gallon reef tank for 2 of the 5 days. Once the temp in the house reached 55 degrees, most everything in the tank was dead. Apart from buying a $1000 generator, has anyone found something lesss expensive to keep things running on the tank during a power outage?
