In The Swim Liquid Sand Filter Cleaner – 1 Quart – Fast-Acting Concentrated Formula for Improved Pool Water Filtration

In The Swim Liquid Sand Filter Cleaner aids in the backwashing process by breaking down oils, non-living organic contaminants, and mineral accumulation. Backwashing alone only removes about 85% of contaminants. The 15% left are oils, grease, non-living organic contaminants, and minerals. Liquid Sand Filter Cleaner breaks up those materials left behind. Allowing a proper backwash cycle. Without those contaminants will continue to build up over time, decreasing flow rate and circulation rate. Eventually causing cloudy green water. In The Swim Liquid Sand Filter Cleaner should be added to the skimmer. Turn on the circulation system. Pour 8 oz of Liquid Sand Filter Cleaner into the skimmer, with the skimmer running on full. Turn the pump off. Allow the Liquid sand filter cleaner to set inside the filter for an hour. Turn on the circulation system with the filter set to the backwash setting. This will stir up the sand and Sand Filter Cleaner. Allow the system to backwash 3 - 5 minutes or until the water runs cleaner. For best results repeat before each backwash.
