Directions for use: This product is designed for use in properly balanced spa water. Spa Metal free is a highly effective metal chelating agent that protects against staining and discoloration from trace metals such as iron and copper. Spa Metalfree should be used as part of a well-designed spa maintenance program. Spa Metal free does not raise phosphate levels in spa water like many other stain and scale products. Note: This product can be used with most sanitizing systems and is compatible with all spa surfaces. Do not use with biguanides.
Directions for use:
