Add to the pool, allow water to circulate for 10-15 minutes, then switch off circulation pump – make sure there is little to no movement of water whatsoever for the next 24 hours. At the same time the next day, vacuum the pool with the multiport valve positioned to ‘waste’ - DO NOT PASS DEBRIS THROUGH THE FILTER.
For best results, ensure your chlorine level is between the recommended 1.0 and 3.0 ppm.
