When choosing the right size heating rod for your aquarium tank, it is important to consider the water capacity of your tank. In the case of the hygger HG Series Pinpoint Titanium Heater, the recommended water capacity for each heater model is as follows:
- Hg-8021: Suitable for 5-10 gallon tanks
- Hg-9021: Suitable for 10-25 gallon tanks
- Hg-802: Suitable for 20-45 gallon tanks
- Hg-902: Suitable for 60-120 gallon tanks
Based on the information you provided, a 20-gallon tank falls within the recommended range for the Hg-8021 and Hg-9021 models. Therefore, either of these two models would be suitable for your tank. It is important to choose a heating rod that matches the size of your tank to ensure efficient and effective heating.
