Detailed Product Description
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 Metal Free 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.
This product can be used with most sanitizing systems and is compatible with all spa surfaces. Please do not use Spa Metal Free with biguanides. 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.
Directions for Use:
- Initial Dose: Add 1 capful (4oz) per 400 gallons directly to spa water evenly around the edge immediately after initial fill and after each drain and refill
- Weekly Maintenance Dose: Add 1oz per 400 gallons (one quarter of the large cap) weekly directly to spa water evenly around the edge
Comes in a 1 liter bottle.
