Pool alkalinity regulators

Alkalinity plays a vital role in balancing pool water. A good level of total alkalinity stabilizes pH, prevents corrosion, limits limescale deposits, and ensures optimal swimming comfort. Our pool alkalinity regulators help you quickly correct low or high water levels and maintain clear, healthy, and balanced water throughout the season.

GUIDE

Balancing your pool water

Keep your water clear and healthy! Check out our guide to analyzing your pool water for simple, essential tips every step of the way.

FAQ

Why is it important to regulate the alkalinity of pool water?

A good alkalinity level (between 80 and 120 ppm) stabilizes pH, prevents sudden changes, and protects your equipment. Unbalanced alkalinity can lead to cloudy water, deposits, corrosion, and discomfort for swimmers.
