Temperature control
There are two important factors which 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. It should be 24-26 °C. Temperatures above 30 °C are a problem and can cause substantial damage to fish and plants. Furthermore aquariums should never be exposed 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 coolers for freshwater and marine aquariums cool between 2-4 °C with the help of cross-flow fans. Due to the air flow the warm water evaporates at the water surface and thus generates evaporative cooling. This is comparable to evaporation cooling a wet body part exposed to the wind.

Temperature control:
By expanding a JBL ProTemp Cooler with the JBL ProTemp CoolControl, the cooler can be switched on automatically if the set temperature at the CoolControl between 18 and 36 °C is exceeded. Once the temperature reduction has been reached or exceeded, the cooler switches off again.

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