The vinyl liner of my pool has developed a coating of material that appears brown against the light blue liner. This
material brushes off easily, appearing as a cloud of dust particles or small white flakes. The material does not adhear
to the acrylic swim current benches. The buildup covers the entire vertical surface of the liner down to the swim current benches,
of course below that I can't see. On the pool bottom, the liner also has buildup adjacent to the swim current benches
where I would not normally walk and an accumulation where a tension strap creates a ridge in the liner probably when
the particles settle after falling to the bottom.
I 'am using a UV sanitizer and Nature 2 beads. Taylor K-1005 kit.
