Stains and Discoloration in a Vinyl Liner Pool | InTheSwim ...
Help, I''ve had a vinyl liner liner in my semi inground pool for 10 years. I use an ionizer so there''s definitely copper and silver that''s used to sanitize the water. Over the last year I''ve noticed the pool liner has lost its blue bright color and has become dull and darker. It has a rough feel as well.
