I had a 12 hour power outtage this winter on my 125g mixed reef. I have a clam, RBTA, snails and hermits. All very sensitive live stock when it comes to power outtages.. I have 5 fish in the tank so it is lightly stocked at the moment.
Everything made it through the power outtage just fine. after about 4- 5 hours I decided to get out the battery powered air pup, and Just dumped the hose below the waters surface and let it bubble. I tested the temp several times with my TDS meter. It got down to 26 degrees Centigrade. it usually runs at 27, so was actually pretty good for 12 hours.
The fish were perplexed that the ocean just suddenly stopped moving. It's weird looking at the tank with now powerheads or pumps on. It looks like suspended animation!
