Two important factors affect the water temperature in the aquarium: room temperature and sunlight exposure. When the room temperature rises significantly in summer, it is crucial to regularly monitor the temperature in the aquarium. A target range of 24-26 °C is recommended. Temperatures above 30 °C are very problematic and can cause significant harm to fish and plants. Aquariums should also never be exposed to direct sunlight. The higher the temperature, the less oxygen, which is vital for the animals, dissolves in the water.

Installation is straightforward: the bracket of the cooling fan is placed on the edge of the aquarium (up to a maximum thickness of 2 cm) and secured with clamping screws. The direction of the airflow is adjustable, and the housing on the bracket can be rotated 360°. The xCooler for freshwater and saltwater aquariums cools the water temperature by 2-4 °C using cross-flow fans. The airflow causes the warm water at the surface to evaporate, creating evaporative cooling, similar to the cooling effect of a wet body part exposed to the wind.

Safety: The water cooler is equipped with a safety cover grid and operates on a low voltage of 12 volts.
