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.

have elevated levels of minerals, you may need to double
