Recently, our contractor were call due to the spoil Mist Jet Filter which Jacuzzi sand filter systems use the oldest method of pool filtration. These filters require a special filter sandwhich is referred to as #20 silica sand. This sand has sharp edges that separate the dirt particles. The dirt is driven through the sand bed and trapped in minute spaces between the particles of sand. Large dirt particles are initially trapped, but as the sand bed accumulates more and more debris, it collects small particles too thus required constant maintenance from them.
It is very important that material suspended in pool water be filtered out to maintain safe and sanitary conditions to keep pool water crystal clear and pump healthy.
