The Perform-max Chemicals Feeder by King Technology offers the versatility of using either chlorine or bromine with a patented performance valve that consistently dispenses the correct amount of sanitizer into your pool. The Perform-max feeder brings you the best in bulk chlorine or bromine feeding. Only Perform-max has a patented performance valve that allows water to continuously erode only the bottom layer of chemical. The valve’s wide range of settings gives you more control without over chlorinating. How does it work? Perform-max offers the flexibility of using either chlorine 1” tablets or 3” Pucks or bromine tablets. Set the dial to maintain the industry standard of 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 along with its durable craftsmanship making it one of the top chemical feeders on the market!
