Aquael Ultra Heater Day & Night

The heater is easy to control using the ONE-TOUCH system that employs a single button surrounded by a ring of LEDs indicating the current and set temperatures.

The electronic thermostat operates with an exceptional precision (+/- 0.25° C) to maintain a constant temperature in the tank. This ensures that even the most sensitive of aquarium animals will stay comfortable at all times. Temperatures can be set in the range between 20 and 33 °C, which means that the heater can be used in treating
various fish diseases, including white spots. In addition, the ULTRA HEATER has a built-in system to prevent overheating of the tank water in hot weather.

Thanks to its unbreakable plastic housing, the ULTRA HEATER is ideal for use in tanks where large and strong fish or even water turtles are kept. At the same time, the heater is totally safe and does not cause burns in even the most sensitive animals, e.g. catfish or rays.

Madison ★★★★★ Oct 21, 2026

Setting the temperature is incredibly easy with the one-button LED system, and it keeps my tank perfectly stable day and night.

Zoe ★★★★★ Oct 20, 2026

The LED ring around the single button makes setting the temperature so intuitive, no more fumbling with dials. It's kept my tank perfectly stable through a cold snap this week, which really impressed me.

Brian ★★★★★ Oct 18, 2026

The one-touch button with its LED ring is so intuitive—I set my tank to 78°F and can check the temp at a glance across the room. My fish have been way more active since I swapped it in, and the heater keeps the water steady even when the room cools at night.
