The Black 400 Micron GeoBubbleTM Solar Cover is an energy-saving solar gain swimming pool cover that cuts energy losses and helps to extend your pool season. The cover acts like a floating solar panel to warm your pool water, whilst reducing evaporation which accounts for around 80% of heat loss. The cover has a black top and underside to increase heat conduction, the 100% opaque material helps control the growth of algae.
