A heater for a reef tank is an aquarium heater that is used to maintain a consistent and warm water temperature in the aquarium. Heaters are an important part of a reef tank set-up as many of the animals that are kept in a reef tank come from warm water environments.
Without a heater, the water temperature in the aquarium would fluctuate and could stress the animals or even kill them.

Conclusion
There are many factors to consider when choosing a heater for your reef tank. The size of your tank, the type of fish and invertebrates you keep, and the temperature you need to maintain are all important factors.
Heaters come in a variety of sizes, shapes, and wattages, so it is important to choose the right one for your particular setup.
When choosing a heater, it is important to make sure that it is fully submersible and has a thermostat. It is also important to choose a heater with a high wattage for larger tanks. Heaters typically range from 25 watts to 300 watts.
Once you have chosen the right heater for your tank, it is important to install it properly. Heaters should be installed in an area with good water circulation. Heaters can be mounted on the side of the tank or placed underneath the gravel.
Heaters are an important part of any reef tank and should be chosen carefully to ensure the health and happiness of your fish and invertebrates.
