How Do You Know The Size Of Aquarium Heaters?

When I bought my 55gal aquarium off of craigslist it came with a small aquarium heater. I want to use it on my 10 gallon aquarium--because it seems like it's for 5-10 gallon aquariums, but I'm not sure. Is there any way to tell what size aquarium is the heater for?

  1. How many watts? Brand?
    ~Without knowing wattage or brand it’s impossible for me to tell you if it is appropriate for a ten gallon aquarium.
    How long is it?

  2. BIGgoura says:

    5 watts per gallon
    will heat the water fast and keep it at a stable temp
    wattage should be printed on the side of the heater, or on a peice of paper just inside the glass housing
