To keep pH from fluctuating after a fresh fill, use pH Lock. This product reduces maintenance and saves time.

pH Lock is specially formulated to lock in the vital pH level of spa water, especially hard water. pH Lock is intended for use in freshly filled spas, but can also be added to existing spa water that is properly balanced.


  1. Add pH Lock according to the following chart. Add directly into the spa.
  2. Turn on jets and allow water to circulate for 15 minutes. Temporary cloudiness may occur, but the water will clear quickly once this product has completely dissolved.
  3. Repeat the application each time you refill your spa with fresh water. It is recommended that you refill every 3 months.

Note: If local water conditions are extreme or your spa usage is heavy, use pH Up or pH Down to bring the pH into the range of 7.2 - 7.8. Once you have achieved the desired pH level, then follow the directions above. Once pH Lock is added, it will lock in the pH level.
