What
size Heater should I use?
The
general rule is to use 3-5 watts per gallon of aquarium water, but
5 watts per gallon is recommended. For example, if you have
a 10 gallon size aquarium, choose a 50 watt heater.
It is also a good
idea to have an additional heater handy in case the existing heater
breaks down.
