Does anyone have any ideas on back up power in the case of a power loss with a reef tank?

By the way its hurricane season so i know my power will be lost. I live in florida.......and we usually go between a day or two at the most without power every BIG storm. :/

yup.......it already been covered ..............but............genpak or battery airpumps from walmart with air stones, cut feeding to minimim if any for a couple days..........and pray
