Pink Algae in Swimming Pools

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
