The water collected by the skimmer or overflow is filtered, then treated by salt electrolysis and returned to the pool.
The treated water is fed into the entire BEACHPOOL floor completely invisibly below the drainage layer using the patented BEACHPOOL technology. The water actively flushes the entire drainage layer and is thus filtered once more.
The water flowing upwards from the bottom carries light dirt and pieces of leaves to the surface of the water - no matter what the depth. This is how a BEACHPOOL cleans itself by the way.
Skimmer / Overflow
Irrespective of the wind, the surface flow carries the sediment to the edge, where it is picked up by the skimmer or overflow.
