I've always wondered if I was the only one who never uses heaters. I live in Ohio, so it's not like it's "hot" here either.I just don't use them. The tanks never get below 74. In the winter though I will hook them up because I don't like when it gets below 72. Other than maybe 4 months out of the year at most I don't use them.
I know this depends on what fish you have, where you live obviously, and if you want their metabolism to be much faster.
