Temperature control
Two important factors affect the water temperature in the aquarium: firstly the room temperature and secondly direct sunlight. If the room temperature in summer increases significantly, it is important to check the temperature in the aquarium regularly. Aim for 24-26 °C. Temperatures above 30 °C are a problem and can cause substantial damage to fish and plants. And never expose an aquarium to direct sunlight. The higher the temperature, the less effectively the oxygen (which is vital for the animals) dissolves.

Easy to install
The bracket of the cooling fan is placed onto the aquarium rim (up to max. 2.4 cm thickness) and fixed with clamp screws.

Cools by evaporation
The JBL PROTEMP Coolers for freshwater and marine aquariums cool between 2-4 °C with the help of cross-flow fans. The air flow helps the warm water to evaporate at the water surface and thus generates evaporative cooling. This is comparable to the evaporation cooling effect when wet skin is exposed to the wind.

Safety
The water cooler has a safety cover grid and is operated with an extra-low voltage of 12 V.
