## Description

Product description Protect your hot tub and equipment from corrosive water with AquaSPArkle Hardness Plus. This fast-acting granular formula quickly raises calcium hardness levels, helping to prevent damage to surfaces and internal components. Ideal for maintaining balanced water chemistry, especially in soft water areas, when levels fall below 100mg/l (ppm). For simple step-by-step guidance, scan the on-pack QR code and follow our handy video instructions! Directions Pre-dissolve AquaSPArkle Spa Hardness Plus in a clean plastic container at a maximum rate of 10g of product per 1ltr of clean cold water. Stir well to ensure product is fully dissolved. Add the resulting solution to the spa whilst the pump(s) are turned 'on'. Next adjust the Total Alkalinity and buffer the pH (this stops the PH value fluctuating rapidly). Finally, adjust the PH and, if required, adjust the Hardness.
