      In The Swim Instant Liquid Acid is a dry granular acid used to reduce pool pH levels, or to remove stains and scale on pool tiles, bricks and stones, or pool salt cells.
       

      Directions for Use
      Balance total alkalinity in pool water to 80-125 ppm for plaster finishes and 125-150 for vinyl, fiberglass and other non-masonry finishes. For most efficient performance of pool chlorine, pH should be maintained between 7.2 and 7.6. Use a reliable test kit to determine pH. If the test shows a pH above 7.6, add this product to the pool water using the chart below as a guide.

      To add this product, broadcast into the deep end of the pool when not in use. Add directly to pool with pump and filter system running. Never add more than 1.5 pounds of this product per 10,000 gallons of pool water at any one time. Allow pool water to recirculate two hours and retest pH. Repeat treatment as necessary. Newly plastered pools may require frequent treatments for the first few weeks while the pool is curing. Do not add near metal fittings or allow pH to drop below 7.2. Do not allow undissolved clumps to remain on the pool bottom. These can be broken up by brushing with a pool brush.
