Biguanide is a type of swimming pool sanitizer that can be used instead of chemical-based sanitizers like chlorine or bromine.
What is Biguanide for swimming pools?
Biguanide is a molecule commonly used for disinfectants, particularly the molecule polyhexamethylene biguanide. This variety of biguanide has become increasingly popular as a sanitizer for swimming pool water, as it is a good alternative to other chemical-based sanitizers like chlorine and bromine.
For this type of water sanitizer, no regulatory standards have been set by government organizations. However, there are a few general guidelines for use. For instance, a major manufacturer recommends that sanitizers containing biguanide may only be best used for swimming pools which are 25,000 gallons and below.
