Aquarium Heaters and Chillers

An aquarium heater and aquarium chiller are used together to maintain a constant aquarium temperature, a necessity for many fish and coral.

Almost every aquarium needs a fish tank heater to raise the water temperature. You will want 3-5 watts of tank heater per gallon of aquarium. The most common, a submersible heater, is placed inside the aquarium or sump. An inline aquarium heater attaches to a filter hose outside the tank. A titanium aquarium water heater is a powerful heating element that needs a separate controller.

We recommend owning an extra fish tank water heater for emergencies and quarantine.

Because reef tank equipment produces a lot of heat, many hobbyists need an aquarium water chiller. Most choose an external fish tank chiller that attaches to the return pump tubing. Some reef aquarists can get by with an aquarium fan, which cools the water through evaporation.
