Natural Chemistry Metal Free 1L

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. This product is compatible with most sanitizing systems and can be used with all pool surfaces except for those treated with biguanides.

Do not use with biguanides.
