Key Features to Consider in an Aquarium Heater
When selecting an aquarium heater for a 20-gallon tank, there are several key features that should influence your decision. First and foremost is the wattage of the heater. A general guideline is to aim for about 5 watts per gallon of water, meaning a 100-watt heater is typically optimal for a 20-gallon tank. This wattage will help ensure that your aquarium maintains a stable and appropriate temperature for your fish and aquatic plants.
Another essential feature is the heater’s type, which can be submersible, inline, or hang-on-back.
