How to keep tank warm when the power goes out?

[Aquarium77]

Hello everyone, there might be a freeze coming where I live very soon, I do not have a generator, and I'm afraid that if my power goes out my fish will freeze. Is there a way to keep them warm if the power goes out? I have 2 tanks, a 10 gallon with just a snail right now, and a 29 gallon with a school of Kuhli loaches, the temp of both tanks is around 79° Fahrenheit. Thank you.

If you can heat water (gas or propane stove) boil water and put in into plastic water bottles. Put bottles in tank when needed. Let the bottle sink.

If you lose power, put blankets over the tanks to hold in the heat. Hand warmers like they sell at gas stations can be taped to the tank. Good luck.

Here's an older thread about power outages and some ideas to help keep everything going. We have them all of the time, so I wrap the tank(s) in blankets, and I have some hand warmers that I can use for heat. I also have some usb powered air stones to help with circulation. Finally, if you have an hob filter, it would be good to pour some tank water thorough it every so often to keep the beneficial bacteria going. I usually pour some water through my hob every 30 minutes or so.

get plaster of paris power from local hardware store. add water and stir (add water and stir until paste-like) in a disposable container with tight lid. then somehow hang in your tank with the container in contact with the water. the reaction between plaster of paris n water generates alot of heat. you may want to test it out first.
DO NOT put bare hands into the mixture. and make sure no kids around you when doing.
i use plaster powder for modelling in art and they are very hot when hardening.
just make sure the powder dont get into the water.
