BrightArk Aquarium Heater 300W digital thermostat 🐟

This 300W aquarium heater brings stable temperature control to freshwater and saltwater tanks up to 250 litres, helping maintain a consistent environment for tropical fish and turtles. It is designed for easy monitoring and routine maintenance, with a visible external controller and a removable protective cover to reduce risk of contact burns.

Key Points

The heater uses an external digital thermostat that displays both current and set temperatures, making adjustments straightforward and visible. The temperature range runs from 18 to 35°C, so you can cover common tropical requirements; this range is stated by the manufacturer and covers typical aquarium setups. The unit includes two suction cups and a 1.9 m power cord for flexible positioning within the tank, and the removable guard simplifies cleaning while protecting aquatic pets from direct contact. 🐟

This model suits tanks between 100 and 250 litres, and the manufacturer notes it is compatible with both fresh and saltwater environments. The heating element is described as impact resistant, which helps durability in everyday use. Consider that for very small nano tanks under 100 litres a lower wattage might be more appropriate, and for very large systems multiple heaters or a more powerful option could be needed.

Usage Recommendations

Install the heater horizontally or vertically as indicated in the manual, positioning it near a gentle flow to distribute warmed water evenly. When placing the heater, use the included suction cups to secure it and allow a short run time before making any major adjustments to the set temperature. Regularly clean the protective cover to prevent algae build-up and check the external digital display to confirm the set temperature remains unchanged after maintenance. 🌡️

For saltwater use, rinse the exterior periodically with fresh water to reduce salt deposits on the glass and connections. Although the quartz glass construction improves impact resistance, avoid sudden strong knocks against hard surfaces when handling the unit. Also note that the thermostat operates within a defined range according to the manufacturer, so if you require temperatures outside 18-35°C you will need a different model or additional equipment.
