Ocean Breeze Cooling Fans
When the sun is out it great for sun worshippers, but not so good for your tank.
Tank temperature can become to warm for many fish and corals, which can cause stress and disease. Not everyone has the budget or space for a refrigerant chiller and so a simple solution is to chill your tank by evaporative cooling.
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 with each fan running on ball bearings, compared with similar cheaper versions where the plastic fan runs directly on the shaft.
This feature adds to the cost but significantly increases the life and reduces noise levels from the fans.
