These aquarium heaters are set with a convenient dial and maintain the desired tank temperature within ±1° C or F. Heaters are fully submersible; feature an on/off light; and are made of heavy-duty, shock-resistant glass. Good for fresh- and saltwater tanks. Available in 25-, 50-, or 100-W output. 8" L.

To determine the heater wattage needed for your aquarium, first subtract the average room temperature from the desired water temperature. For example, if the average room temperature is 68° F and the desired water temperature is 77° F, then the heater needs to heat the water 9° F to maintain the desired water temperature. Now, consult the data below to determine the wattage needed to maintain the desired water temperature in your tank.

For a 5-gal aquarium, 25 W is needed to heat the water 9° F above average room temperature, 50 W to heat it 18° F, and 75 W to heat it 27° F.

For a 10-gal aquarium, 50 W is needed to heat the water 9° F above average room temperature, 75 W to heat it 18° F, and 75 W to heat it 27° F.

For a 20-gal aquarium, 50 W is needed to heat the water 9° F above average room temperature, 75 W to heat it 18° F, and 150 W to heat it 27° F.

For a 40-gal aquarium, 100 W is needed to heat the water 9° F above average room temperature, 150 W to heat it 18° F, and 300 W to heat it 27° F.
