Maintain stable, sparkling water with Quick Dissolving Alkajuster, available in 750g, 4kg, 8kg, and 22.6kg sizes. This fast-dissolving total alkalinity increaser (sodium bicarbonate) raises and stabilizes alkalinity levels in spas, above ground pools, and inground pools — helping prevent pH fluctuations and protecting your equipment.
Total alkalinity should be maintained between 100–150 ppm. When alkalinity is too low, pH levels swing unpredictably, reducing chlorine or bromine efficiency and increasing the risk of corrosion, irritation, and surface damage.
Why Use Alkajuster?
✔ Stabilizes pH levels
✔ Improves sanitizer performance
✔ Protects heaters and metal components
✔ Prevents corrosion and surface etching
✔ Suitable for all pool and spa types
✔ Fast-dissolving granular formula
Regular alkalinity maintenance is one of the most important steps in proper water balance.
Directions for Use
To raise total alkalinity by 10 ppm, broadcast:
18 grams (1 level tablespoon) per 1,000 litres of water
Allow water to circulate fully before retesting and adjusting further if needed.
Average Seasonal Usage Guide
