Product description

Installation tips

It is recommended that the heater be fully immersed in water and placed in an area with good water circulation, such as near a filter intake or water pump, to minimize temperature error.

Aquarium Heater Size Guide

To calculate the required power for the aquarium heater, follow these steps:

Measure the actual dimensions of the fish tank, including the length (L), width (W), and the height of the water level (H).Use the following formula to calculate the required power: Required Power = (L × W × H / 231) × 5

Situations requiring a larger heater include no cover or near an external wall/door, room temp <65°F, and ≥15°F water temp increase.
