A digital thermometer is a relatively cheap $8 investment that eliminates the guess work. Don't really on the setting scale on the side of the heater. They are generally not that close. As I understand it, the "heater rule" is 3 to 5 watts per gallon. We aren't exactly in a cold area though and you might be ok with that heater if you are indoors. I would definitely get rid of that hose.
