Basic Pool Care Using Biguanide (Baquacil)

One of he most commonly used alternatives to chlorine is Biguanide, which is based on European technology and has been used in the Denton area since approximately the late 1980’s. it is a disinfection system that is incompatible with chlorine, bromine, non-chlorine chock, copper based algaecides, as well as other chemicals.
            The Biguanide disinfectant is used in conjunction with hydrogen peroxide (for oxidation purposes) and a quat-based algaecide. The product is a disinfectant that destroys bacterial cell membranes, and depends heavily on the filter to maintain a clear pool. This product can be effective in the right situation but is slightly more expensive than chlorine. Although it will work in all types of pools, the ideal pool for the product is a vinyl-liner pool with a sand filter. It is tested with a test kit that is designed for Biguanide testing.
