It is very important that you purchase a
good quality submersible heater with a thermostat when setting up your
aquarium. Cheaper does not necessarily mean better when it comes to
aquarium heaters. If you buy a cheap heater and it stops working, it could
cause all of your fish to die before you realize that there is a problem.
Use the chart below to determine what size heater is necessary
for your new aquarium.
