Natural Chemistry's METALfree is a highly effective chelating agent that prevents staining and discoloration from trace metals such as iron and copper. METALfree also prevents scale build-up due to calcium and other minerals. These trace metals and minerals may already be in the pool water or in the fill water. It should be used as part of a well designed pool maintenance program where local water requires it, or where well water is the pool water source.

Please Note: METALfree does not contain phosphonic acids and will NOT raise phosphate levels in pool water.

Initial Dosage:

Add 1 bottle per 20,000 gallons to the pool water evenly around edge.

Weekly Maintenance Dosage:

Each week, add 1 capful (4 oz) per 10,000 gallons to the pool water evenly around edge.
