Better Spa Water Starts with Stable Alkalinity

Zodiac Spa Alkalinity Up raises Total Alkalinity and pH in spa water, helping make everyday water balance easier to manage. Correct alkalinity provides the buffering capacity needed to keep pH more stable and gives spa sanitisers the right water conditions to work effectively.

When Total Alkalinity is too low, pH can move up and down quickly, making the spa harder to balance. By correcting low alkalinity, Spa Alkalinity Up helps support bather comfort and balanced water conditions for spa surfaces, fittings and equipment.

Features & Benefits

  • Corrects Low Alkalinity: Raises Total Alkalinity and pH when spa-water levels are below the recommended range.
  • Steadier pH Control: Improves the water’s buffering capacity to reduce rapid pH movement.
  • Better Sanitising Conditions: Balanced water helps spa sanitisers work more effectively.
  • More Comfortable Spa Water: Supports balanced conditions for improved bather comfort.
  • Surface & Equipment Care: Helps reduce corrosive water conditions associated with low alkalinity and low pH.

How to Use

  1. Test the spa water to determine the current Total Alkalinity and pH levels.
  2. Calculate the required dose based on the spa volume and the required Total Alkalinity increase.
  3. Fill a clean bucket with spa water, add the measured product to the water and stir until dissolved.
  4. With the pump and filtration system running, apply the dissolved solution evenly around the edges of the spa.
  5. Keep the spa cover off for at least 30 minutes after application and continue running the filtration system for 4–6 hours.
  6. Test the spa water again before adding another dose.

Dosage & Coverage

  • Standard Dose: Add 20g per 1,000 litres of spa water to increase Total Alkalinity by 10ppm.

Important Usage Information

  • Do not add more than 200g per 5,000L in any 6-hour period. Large additions may increase the risk of metals plating onto spa surfaces if metals are present in the water.
  • Do not add Spa Alkalinity Up within 2–4 hours of adding Spa Calcium Up or another calcium hardness increaser, as this may cause extremely cloudy water.
  • Do not mix directly with other spa chemicals.

Maintain Total Alkalinity between 80–120ppm and pH between 7.2–7.8.
