Maintaining correct water temperature is an essential requirement for keeping fish happy and healthy, especially in tropical aquariums and even for Betta Fish and in smaller aquariums!
Aqua One makes it easy to maintain the correct temperature with the Betta Nano Preset Heater! Providing precise preset temperature and supreme durability, you will be on your way to professional fish keeping in no time!
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.
