I, like quite a few others, were in the path of Irene. Our power went out 8 AM on Sunday morning, August 28. We were lucky and power was restored 2 PM Monday afternoon, the next day.
As warm as it was, tank water temp was not a problem. I did a very large water change Saturday, the day before the 'cane so no problems there. Come Monday though, I think oxygenation of water could become a problem. I do not have battery operated air pumps.. but I had a better idea (which I did not utilize as the power returned.)
I homebrew. One of my many beer gadgets is an oxygenation system which utilizes regular O2 in a tank one can buy from home depot. These tanks are used in small oxy-acetylene torch systems.
All you need to do is to hook one of these O2 tanks up to an airline with an airstone and let her rip for 5 minutes or so. It only takes about 3-4 to oxygenate a wort adequately so the yeasty beasties have a field day making beer. It is possible large fish tanks might need as much as 10 minutes. It only takes about 3 minutes to properly oxygenate a 5 gallon batch of wort so the yeasty beasties can have a field day making beer.
Just food for thought here.
What do y'all think??
