💬 Southern Leisure Says

Raise low pH gradually. Add the measured amount, allow the spa water to circulate and retest before adding more. Overcorrecting the water can require additional chemicals to bring the pH back down.

  • Use a clean, dry measuring tool.
  • Keep the container tightly closed and dry.
