How each product helps

Chlorine Granules (500 g)
A fast-acting hot tub sanitiser for clear, safe water. Maintain a 3-5 ppm residual to control bacteria and help the water recover quickly after use.

pH Plus Granules (500 g)
Raises low pH into the recommended 7.2-7.6 range. Correct pH improves sanitiser efficiency and helps protect heaters, pumps, seals, and acrylic from corrosion.

pH Minus Granules (750 g)
Lowers high pH to prevent scale, cloudiness, and irritation. The 750 g size reflects real-world dosing needs, especially on fresh fills and in hard-water regions.

Total Alkalinity (TA) Increaser (500 g)
Establishes the correct alkalinity buffer, typically 80-120 ppm, to keep pH from drifting out of range. Stable TA makes ongoing water care easier and helps protect spa equipment.
