When temperatures start to rise and a chiller isn’t an option then a cooling fan can help your aquarium.
This low cost solution simply involves blowing a stream of air over the surface of your tank or sump to increase evaporation, which creates evaporative cooling.
There are plenty of low cost fans on the market however the OCEAN BREEZE units are different, using quality caged ball bearings, rather than the plastic fan running directly on the shaft.
