The quantity of DE used is predicated on the dimensions and particular mannequin of DE filter. When the preliminary DE is put within the pool, and the pool pump and elements are working correctly the stress on the stress gauge is famous.

Because the DE will get soiled, the water stress builds up and the stress gauge rises, indicating the necessity to backwash. Backwashing is when the circulate of water is reversed and the water pushes the filth and particles out of the filter. Backwashing pumps out not solely the filth but additionally the DE.
