The specially treated alloy cylinder is packed with KHF granular formulation. These minerals dissolve from the cylinder and form a stable residual throughout the pool water for up to 6 months. The minerals eliminate algae while helping low levels of chlorine stay more active and productive in the water. During the pool's filtration process, the minerals are rejuvenated every time they return and pass through the cylinder. KHF works with a constant low level of chlorine.\u003c\/p\u003e\n\u003ch4\u003eAlso ideal for salt pools\u003c\/h4\u003e\n\u003cp\u003eKHF improves the saltwater experience. The minerals reduce salt chlorine production needed to help keep a salt pool algae free. Less salt chlorine production can extend the life of the salt cell and reduce the amount of acid needed to balance pH.
