How each product helps

Bromine Granules (500 g)
A reliable hot tub sanitiser that performs across a wider pH range and feels softer in use. Maintain a 3-5 ppm residual for clear, safe water.

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 (80-120 ppm) to stop pH drifting out of range. Stable TA makes ongoing water care easier and helps protect spa equipment.
