Metalfree is a highly effective metal chelating agent that protects against staining and discoloration from trace metals such as iron and copper. Metalfree should be used as part of a well designed pool maintenance program. Metalfree does not raise phosphate levels in pool water like many other stain and scale products.
Note: This product can be used with most sanitizing systems and is compatible with all pool surfaces. Do not use with biguanides.
Directions for use:
Initial Dose: Add 1 bottle (1L) per 75,700 litres to the pool water evenly around edge.
Weekly Maintenance Dose: Each week, add 1 capful (120mL) per 38,000 litres to the pool water evenly around edge.
Do not exceed recommended dose.
Note: Take caution to not spill or splash Metalfree on deck or coping.
