Acid-Rite® 450 Water pH Adjustment System – Compact Sodium Bisulfate Tablet Feeder

The Acid-Rite® 450 Water pH Adjustment System provides a compact and efficient alternative to bulky liquid acid feeders, making it ideal for facilities with limited pump room space. Designed for both indoor and outdoor commercial pools, the system uses patented red Acid-Rite sodium bisulfate tablets to lower pH and optimize chlorine effectiveness without the strong odors, spills, or corrosion risks associated with muriatic acid.

The unit’s low-maintenance design and controlled pH adjustment improve operator safety and simplify maintenance. With a capacity of up to 45 pounds of tablets and a maximum flow rate of 5 gpm, the Acid-Rite 450 can handle pools up to 300,000 gallons indoors and 200,000 gallons outdoors. Its red tablets ensure clear chemical identification to prevent accidental mixing.

A safer, cleaner, and easier way to manage pool water balance — no mixing, no metering, no hassle.
