guys, about your fish, the best protection is a generator. However, If you're not about to get your hands on one. You can last about a few days just doing the pouring a gallon or so of water from your tank into your tank. But do it like 5 times in a row and your good for about an hour (depending on fishload etc.) I also had about 20 gallons of water made, and I did water changes when my parameters got bad. I kept the old water, filtered it through a filter sock and used Prime. The real issue was for us down here in the south was heat. That is what eventually got me. I tried 2 liter frozen water bottles. What I'd do differently would be to use evap as a cooler, you know like those algae mats?
