How to keep tank warm during power outage?
Last evening out power went out. We do have a generator but it's difficult to set up and get going--in the future we're going to be smarter and set it up when we hear there is going to be a big storm but this time we didn't--and it was dark so we couldn't really do it. We were planning to get it going in the morning but thankfully the power came back.
But it got me thinking, if you don't have a generator, what do you guys do for your fish tanks? Mine dropped 4 degrees in about 4 hours. It was a 74 and it got down to 70.
I decided to take a chance and siphon out some of the tank water, heat it over the stove (thankfully mom has a big pot she uses to boil cans for canning in that has only even seen water, nothing else in it), then siphon out some more tank water into the pot to get a more neutral temp and then carefully add it back into the tank.
This did bring the temperature back to about 73-74. And thankfully power came back on at 3:30am. But I'm not entirely sure this was really a very wise thing to do. My thinking was they're going to get too cold. If it's dropping 1 degree/hour then by morning, or at least when the sun starts to come up so we can put the generator on--which is like just about 7am this time of year, it's going to be at 62 degrees or there abouts. So I felt I had to try something.
But I am concerned that by adding the water back like that it was a relatively abrupt change in temperature back up to a little over 73 degrees from 70. This is all Fahrenheit by the way.
Thankfully my fish seem to have survive the night and are doing pretty well today. Hopefully they'll be alright. But what is a better way to deal with this? Or do you all just have generators?
In the future we'll definitely have a generator set up before hand but you never know when someone crashes into a telephone pole or something, we might lose power when we don't expect it etc.
