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.
These Blue Planet aquarium water 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.
SIZES: 25W; 50W; 100W; 150W; 200W; 300W
