Swimming pools located in areas with large amounts of dirt, sand or other small debris require regular vacuuming in order to stay clean. The debris entering the pool system clings to the pool walls or settles out onto the pool bottom over time. Vacuuming up the dirt and debris sends them to the pool's filter or waste line for removal. Fine dust or other very small particles require repeated attempts at vacuuming or application of flocculant chemicals in order to be removed.
Scrub the sides of the swimming pool vigorously with a pool brush to dislodge any dirt or debris clinging to it. Utilize a brush with metallic bristles to scrub away any stuck-on dirt or debris.
Pour 3 oz. of a pool water clearing agent or clarifier into the water for every 10,000 gallons of water in the pool. Circulate the pool for several hours while the chemical drops any suspended particles of dirt or debris to the pool bottom.
Hook up the pool vacuum system used with the pool. Run the vacuum's head over any areas of the pool floor covered in dirt or other debris. If the dirt or debris becomes agitated and free-floating, allow the pool to circulate and the debris to settle on the bottom of the pool floor before continuing.
