Aqua One Aquamanta 500W Quartz Glass Aquarium Heater 46cm

Our pet fish originate from all over the globe and water temperatures can vary greatly between their different native environments. To be able to keep fish in an environment that is consistent with their natural habitat, we often need to maintain water temperature above normal room temperature. Temperature extremes and fluctuations make fish susceptible to stress and diseases such as white spot (Ick!). An aquarium heater is a must-have to prevent your water temperature from dropping too low or changing too quickly.
The Aqua One Quartz Glass Heater range has a sensitive and reliable thermostat that will keep your water at the perfect temperature for your fish throughout the cooler months. Easy to install and use, it will regulate the water temperature for your fish and ensure your aquarium is protected from the effects of low or fluctuating temperatures.
The Bonus protector insulates your heater from aggressive fish who try to smash heaters in your tank.
