Chlorine is the most popular treatment for keeping swimming pool water chemistry balanced because it's highly effective and relatively low cost. Other disinfectants include bromine, ozone, and ultraviolet (UV) radiation.

Unlike manually dosed chlorine, but similar to saltwater pools, a mineral pool system uses a blend of naturally sourced minerals to help disinfect your pool. These minerals – usually magnesium, potassium and sodium chloride – dissolve in the pool water before passing through a chlorinator.

There are three main types of swimming pool water systems: chlorine, saltwater, and mineral. Below we'll break down the advantages and disadvantages of each type and what might be best for each type of swimming pool.

Pool chemicals are used to maintain swimming pools and spas to reduce germs and other microorganisms in the water and keep the pool looking clean. These products include sanitizers, algaecides, pH balancers, clarifiers, and shock. Pool chemicals are an important tool to protect the health of swimmers.
