Aquarium Heaters

Aquarium Heaters


Using the Aquarium Heater Size Guide below, find the size of your aquarium in the left hand column and move to the column that shows the number of degrees the aquarium needs to be heated. If the heating requirement is between levels, move up to the next larger size.

In larger tanks, or where the room temperature is significantly below the desired water temperature, two heaters may be required. Heaters should be installed at opposite ends of the aquarium to heat it more evenly.

Average Room Temp = 68 degrees F
Desired Water Temp = 77 degrees F
Heating required = 9 degrees F

Tank Size = 20 gallon
Heater size needed = 50 watts
