High alkalinity can make it difficult to adjust pH. 2KG.

  4. Continue filtration and re-test after 15 minutes.
  5. Repeat the treatment until pH falls within the range 7.2 - 7.6.
  6. To reduce the alkalinity, temporarily stop the circulation, double the dose rate and add to spa water in one area. immediately restart the circulation. Repeat the procedure as required.
