Pentair offers a variety of products designed to help pool owners maintain a healthful and sanitized pool environment. For keeping your pool sanitized with a minimum of inconvenience, you can't beat an automatic chlorine/bromine feeder. These completely enclosed systems are NSF-listed and can be installed in new or existing residential or commercial pools. Simply fill with bromine tablets or slow dissolving chlorine tablets, and the feeder will automatically dispense a constant feed of sanitizing chemical to your pool.
