Aqqa Intelligent External Controller Aquarium Heater

If you need more consistent water temperature in a larger aquarium, this aquarium heater is a high-power tank heater designed to bring water up to the set temperature quickly and keep it stable. The chrome-nickel heating element and an intelligent external controller start heating automatically if the water is about 2°F/2°C below the set point, making it suitable for both saltwater and freshwater setups when matched to the recommended tank size.

The heater offers practical safety and efficiency for routine tank maintenance. Dry-burning protection cuts power if the probe detects the water surface about 1 inch below the top and resumes when fully submerged, while overtemperature protection stops heating if the water exceeds the set temperature by 3°F/3°C and triggers a high-temperature alarm when nearer to that threshold. Temperature control is accurate to about ±1°C, which helps keep conditions steady and can reduce energy use compared with conventional heaters. Basic care notes: inspect the quartz glass tube for cracks before use, disassemble and clean every 1-2 weeks, do not bury the unit, and run it with a water circulation system such as a wavemaker or filter. For practical sizing, this high-power 500 W option is intended for tanks in the region of 200-300 litres; choose heater power to match your tank and setup.
