Maintaining proper pH levels is an important part of spa maintenance. Imbalances in pH levels can decrease sanitizer effectiveness and lead to scale formation and corrosion on internal parts of the spa. Healthy spa water should have pH levels between 7.2-7.8. Keep your spa’s alkalinity in check to ensure smooth operation all year long.

Use FreshWater pH Up to increase pH levels when they dip below 7.2. To decrease pH levels, you will need to use FreshWater pH Down/Alkalinity Down. FreshWater pH Up is compatible with chlorine, bromine, ozone, and biguanide sanitizers.
