The pH Upgrade Kit is an optional accessory to the Hayward AquaRite+ Chlorinator. The kit assesses the pH level of the pool's water and automatically calculates and injects the necessary amount of acid needed to bring the body of water to ideal acidity levels. Once the pH Upgrade Kit is installed, the optional ORP Upgrade Kit can then also be installed to measure the quality and/ or the ability of the chlorine present in the water to oxidise or burn up unwanted substances into the water and then automatically activate the TurboCell to produce chlorine when the level is reducing.

Maintaining safe water pH levels is imperative to the longevity of the pool structure and mechanical equipment, as well as the physical heath of pool users. If the water is not balanced, bathers are at risk of experiencing forms of discomfort such as skin rashes and sore eyes. Acidic or basic pool water also affects chlorine production efficiency and the elimination of algae and bacteria. It is recommended that the pool water remains at pH levels between 7.2 and 7.8. This allows the chlorinator to work effectively and avoids any corrosion or scale damage to the pool/ spa and associated equipment.
