Swim N Spa Spa First Step eliminates water discoloration caused by mineral and scale deposits in swimming pool water. Also helps to remove deposits that have already formed.
DIRECTIONS FOR USE To prevent staining, water discoloration and scale build-up, add 1 qt. per 10,000 gallons each time swimming pool is filled or add at initial spring startup. *Use Swim ‘n Spa Protect to maintain pool between fillings. First Step should be added directly to pool water while walking around the perimeter of the pool. Wait at least three hours before adjusting pH, do not chlorine shock for at least 48 hours. Vacuum and backwash as needed. If you use well water or your municipal water is known to have elevated levels of minerals, you may need to double the dose to prevent staining and scaling in a properly balanced swimming pool.
Note: Spa Sauna Direct only ships pool and spa chemicals within the continental United States.
