How do I choose the right heater size for my aquarium?
To choose the right heater size for your aquarium you must match the tank's volume in litres to the heater wattage. For instance, a 25-litre tank should use a 25 watt heater, for a larger tank of 300 litres, consider a 300w option. Check the specifications of your fish tank to ensure you're buying the right type.
For further insight into how to pick the right heater for your tank, head on over to our blog for more information.
