Size Guide:

When selecting an appropriate heater size 1 Watt (1W) per 1 Litre (1L) of water is recommended as a starting point. (eg. a 150W heater is suitable for aquariums up to 150L).
Wattage indication is a guide only. Always monitor for consistent aquarium temperature using an aquarium thermometer, sold separately.
If temperature does not hold constant even temperatures, consider increasing wattage of heater.
Seasonal temperature changes or cold houses may cause temperature fluctuations.
