Interesting stuff on Reef Central
Are you prepared for a power outage
These little pumps are awesome. They only come on when the power is off and run for 6 hours on a D cell battery
You have to buy an airline and airstone for them but it has been suggested that you run them high up in your tank so they dont circulate organic laden water near the bottom of your tank. Assuming you don't have your pump on to get rid of it
For a very interesting thread for preparing for a power failure check out this thread. Its got everything from windmills to inverters
