pH & Alkalinity reducer is used to reduce the pH& Alkalinity balance of the water in your Spa/Hot Tub.
The correct pH and Alkalinity balance is vital to ensure comfortable bathing conditions, maximum efficiency from the sanitiser and to help maintain the fabric of the spa and hot tub. The correct pH reading should be between 7.4 – 7.6 and Total Alkalinity between 80 – 150ppm.
