Perform-Max offers the flexibility of using either chlorine 1″ tablets or 3″ pucks or bromine tablets. The in ground model holds 10 pounds. Set the dial to maintain the industry standard 1-3 ppm of chlorine or bromine and refill when empty. For bromine users, bleed the air to create a soaking environment that works best with bromine. Perform-Max's greater adjustability with 9 precise dial settings and an erosion design that wets only the bottom layer of chlorine along with it’s durable craftsmanship make it one of the top chlorinators on the market.
