Let’s start by saying there is no such thing as “Pink Algae”. What is referred to as pink algae is actually a bacterium. While pink algae are rare in pools it can occur, attaching itself to principally to PVC plastics as well as the pool surface. The Pink Algae forms a protective coating, which makes removal somewhat more challenging. It should be noted that pink algae thrives in a dark environment, particularly in areas with slow moving water
How do you get rid of pink algae in pools
Since Pink algae are not algae, shocking the pool in most cases will not solve the problem. The use of a product called Yellow Out is recommended, Yellow Out is not an algaecide, it is a patented chemical that when used in conjunction with chlorine will eliminate the pink algae.
