So being that the weather is bad and there is a possibility of losing power for a few hours or more I thought I would ask about what people do during one. For my 40 breeder I have a battery powered air pump and but wanted to know how others get heat into their tank. I have a gas stove and if needed could heat water but don't know how to transfer that heat to my tank. I was thinking of using a aluminum or plastic water bottle with warm water in it, but I am unsure if this is a bad idea or not. So any thoughts or ideas are greatly appreciated, thanks all.
