the room is warm all the time cause the door is shut but i hhavent done anything since the power went out and the only reason it did is cause the land lord didnt pay the elec bill ( we just pay rent and they pay the rest ) so if i lose any i can make her pay for the fish i lost
don't just leave it up to chance. As long as the temperature doesn't change TOO much, you will be fine with the bucket advice. It's free and easy. Just make sure you add a little dechlor.
