How To Determine How Much Heater You Need For Your Tank

Keeping your aquarium at constant temperature is essential for maintaining good aquatic health. A tank that is too warm promotes algae growth and a tank that is too cold encourages growth of parasites. Below is a general guide for determining the size heater you will need to keep your aquarium at a constant temperature.

Instructions:
Subtract the average temperature of the room the aquarium is located in from the temperature you wish to maintain the aquarium water at. 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.
Example:
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 watt
