Hi all, brand new to the site, a division I have about a year of experience with freshwater. I just recently was blessed with quite a few pieces of equipment at no cost. I am upgrading my freshwater from a 30 tall to a 55. I have a sump that I believe is 15 gallons and a fluval 304 canister. I would like to run both and a separate refugium. I just can't figure out a good way to protect against a power outage seeing as how the sump as well as the fluval are both syphon fed. Any advise would be appreciated. Thanks alot.
