poolrx 101067 Black Units (4 Pack) 20,000-30,000 Gallon Spa Unit 400-1,000 Gallons Bundle

This pool care bundle contains 4 units of PoolRx 101067 Black Units Swimming-Pool-Algaecides for pools up to 30,000 gallons each, plus 1 unit of PoolRX+ spa for spas and small pools up to 1,000 gallons. Together these products simplify pool and spa care by eliminating all types of algae for up to 6 months, reducing the need for extra chemicals, and improving water quality. The PoolRx black units use a proprietary mineral blend packed into an alloy cylinder that is simply placed into the pool's pump basket or skimmer. As the water flows through, the minerals are continuously released to prevent algae growth in up to 30,000 gallon pools for up to 6 months. The PoolRX+ spa unit uses a formula with 3 active ingredients to achieve similar algae prevention and water quality improvement in smaller 400-1,000 gallon spa pools for up to 6 months. It is NSF/ANSI 50 certified to simplify spa care. With both products lasting up to 6 months, this bundle provides an effective, simplified system to keep pools and spas clean and algae-free throughout the swimming season without the hassle of frequent chemical treatments.
