Aquael ultra heater 75W - Day and Night

The Aquael Ultra Heater Day & Night allows you to replicate natural diurnal temperature changes in your aquarium. Thanks to the innovative Day&Night system, temperature automatically adjusts based on ambient light levels.

Simply choose the desired mode and set the temperature. In the evening, a light-sensitive sensor activates the night mode, gradually cooling the water to the night setting. As daylight returns, the heater warms the water back up smoothly to the daytime setting.

Precise and Gentle Temperature Regulation

Sudden changes in temperature can cause stress or illness in aquatic animals. That’s why the Ultra Heater features a highly accurate electronic thermostat with a precision of ±0.25 °C.

Thanks to the Smart Heating system, temperature adjustments happen gradually, ensuring your fish and other creatures experience a stable and stress-free environment. The heater operates within a safe range of 20–33 °C.

Safe for All Aquarium Inhabitants

The heater distributes heat evenly, regardless of tank size. Its casing is made of unbreakable plastic that remains cool to the touch, making it a safe choice even for tanks with large fish or aquatic turtles.

User-Friendly Design

With its slim, modern design, the Ultra Heater doesn’t take up much space in the tank. An easy-to-read display shows both the current and target temperatures.

The heater includes a double-sided mounting system with suction cups, allowing flexible installation on any aquarium wall. The thermostat display remains clearly visible no matter how you mount it.

Energy-Efficient Technology

Thanks to the Smart Heating System, the heater automatically adjusts power output to maintain the set temperature efficiently. This reduces energy consumption while keeping the aquarium environment optimal.
