quael ULTRA HEATER DAY&NIGHT is a heater that evenly heats the water in the aquarium for the most sensitive species. It allows you to set the temperature every 1°C with a precision of up to 0.25°C. The heater is equipped with a thermostat that helps maintain a constant temperature in the aquarium. If the water temperature drops by 0.25°C, the heater will automatically increase the temperature to the indicated level.

Thanks to the Smart Heating system, water is heated smoothly without exposing the aquarium inhabitants to additional stress caused by sudden temperature changes. Thanks to its housing, the heater is very safe, especially in an aquarium with demanding and sensitive species. It does not burn or break. The housing is made of durable and solid (heavy) material, attached with a convenient double-sided hanger with suction cups, which allows installation on the front or back wall of the aquarium, with the front (controller) facing the observer.

The Day&Night system is equipped with the aim of reproducing the natural thermal conditions that prevail in waters both during the day and at night. You must turn on the appropriate operating mode and program the temperatures at which the heater operates during the day and at night.

When the built-in sensor detects a limited amount of light at night, it will automatically activate the night mode, gradually lowering the temperature to the indicated level, while it will gradually warm up during the day.
