ABSTRACT:
A method of controlling the growth of bacteria and algae in the water of swimming pools by adding to the water a specified concentration of a polymeric biguanide. Has the advantage over chlorination that at the low concentration employed the polymeric biguanide is non-toxic, non-irritant, tasteless and odorless. The anti-bacterial and anti-algal effect is also highly persistent.
