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.
Neutralizes iron, copper and other trace metals that can affect clarity
Note: Cationic polymers used in many clarifiers, flocculants and polyquat algaecides should not be dosed to swimming pool water at the same time as metal control products. Cloudy water, precipitation and reduced product effectiveness may result. Wait 24 hours between additions.
