After quite a battle this year.. me against, farm pond green, nasty water (my fault).. I have clear water but light brown (tan) stains on the liner (24 ft AG pool). I read TPF's "directions to use Ascorbic acid to rid your pool of metal stains"...
How soon is it safe to get in the water after treating for stains..
and If we choose to just live with the stains.. are they harmful to swimmers.. and will they get worse?
