Pool Filters - sand pool filters, care and repair information page .
The sand in a pool sand filter (#20 silica sand; 45 - 55 mm) is specially graded to trap particles in the 20 - 100 micron range. As a sand filter collects dirt, its efficiency increases, trapping more dirt. When your pressure gauge shows a reading 8 - 10 lbs. over the clean, start-up reading, it is time to backwash the captured dirt.
