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.
