This product is chemically formulated to break down caked on oils and minerals on your sand filter, allowing them to be backwashed away. This results in a “like new” filter performance.
- While the filter is backwashing, slowly pour 8 fl. oz. of this product into the skimmer.
- Continue the backwashing process according to the manufacturer’s instructions.
- Can be used every time the filter is backwashed to maintain filter efficiency and a crystal clear pool.
