Water temperatures in aquariums should never exceed the 30 °C mark. Fish and plants can tolerate it for a short time, but the invertebrates in seawater soon die off if the water temperature exceeds 30 °C. The JBL fans (JBL PROTEMP COOLER) easily and efficiently lower the water temperature by about 4 °C. The air flow generated creates an evaporative cooling effect on the water surface, similar to the cooling effect of holding a wet arm in the wind. The JBL PROTEMP COOLER is available in 2 sizes and with the JBL PROTEMP CoolControl , a thermostat for automatic operation is also available. This video shows the JBL PROTEMP Cooler x300 (Gen 2) , which is 27 cm wide.
