AquaEL Ultra Heater D&N

The AquaEL Ultra Heater Day&Night is an aquarium heater in an unbreakable housing that reproduces the daily temperature changes found in nature. In the evening a sensor reacts to the fading light and the water cools gradually to the set night temperature; in the morning it warms up again to the day temperature.

The heater comes in six wattages – 25 W (10–25 l), 50 W (15–50 l), 75 W (35–75 l), 100 W (60–100 l), 150 W (90–150 l) and 200 W (130–200 l). According to the manufacturer, the electronic thermostat works to within ±0.25 °C between 20 and 33 °C, and the Smart Heating System warms the water smoothly. The unbreakable housing does not heat up, so the heater also suits aquariums with aquatic turtles and large fish.

Choose the mode and programme the temperature; the display shows the current water temperature and the set range. The flat heater attaches to a double-sided hanger with two suction cups, so it can go on the back, front or side wall of the aquarium.
