Spa Fresh Ultra pH & Alkalinity Up 1kg

Product Description 

Spa Fresh Ultra pH & Alkalinity Up 1kg is a water balancing treatment designed to raise both pH and total alkalinity levels in spa and hot tub water. Maintaining correct water balance is critical for protecting spa equipment, maximising sanitiser efficiency and ensuring a comfortable bathing experience.

Low pH and alkalinity can result in corrosive water that may damage heaters, pumps, jets and other spa components while causing skin and eye irritation. Spa Fresh Ultra pH & Alkalinity Up helps stabilise water chemistry by increasing alkalinity, reducing pH fluctuations and creating a more balanced water environment. 

Regular testing and adjustment of spa water helps maintain optimal water quality, protects spa surfaces and improves the effectiveness of sanitising systems.
