Aquarium Heaters Range

Why do you need an heater

If you have a Tropical, Marine, or Reef aquarium then you will require a good quality fish tank heater.

Importance of temperature

Maintaining a stable temperature is necessary to create a healthy environment for your fish. Temperature fluctuation causes stress to your fish and corals which can lead to disease and possible death of your aquarium inhabitants.

Different kinds of fish, corals and other aquarium inhabitants need different temperature ranges.

Please consult with your local aquarium shop, fish breeder, or fish enthusiast for more information or you can refer to our topic on "Aquarium Thermometers" with a table showing approximate water temperature ranges your aquarium inhabitants.

Choosing the right sized heater

Fish tank heaters come in sizes ranging from 25 watt to 300 watt.

In Australia the rule of thumb to work out the correct sized heater for your aquarium is:

For Freshwater

• 1 watt per litre of aquarium water
  Example: 100 litre aquarium = 100 watt heater

For Saltwater

• 2 watt per litre of aquarium water
  Example: 100 litre aquarium = 200 watt heater

Note that larger fish tanks may require more than one heater.
