Spa Metal Free Helps Protect Against Metal Staining
Spa Metalfree 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 Metalfree 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.
Add one capful (4oz.) per 400 gallons, (1oz. per/100 gal) directly to spa, immediately after initial fill and after each drain and refill.
NOTE: Do not add this product through skimmer or on the same day a water clarifier has been added.
