AG Liner Stains.. are they harmful?

[chuck9997]

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"...

2 questions..
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?

First, the stains aren't harmful at all. They just don't look pretty.

Have you determined that they're metal stains and not organic stains?

Once the pH and FC are back in range it's safe to swim.

actually I haven't determined organic or metal... But I will. I am not overly concerned.. they don't really bother me and aren't that un-pretty. In the determination test.. I use a vitamin C tablet.. Where do you get those?.. Just a regular tab like they sell in the vitamin dept at WALMART, etc? Or is it some kind of a big tablet for rubbing?

From other descriptions (found on this message board).. I am kinda leaning towards metal. Although I have never had any metal problems before.. never in 6 or 7 years. I first thought organic.. but the high CL levels I had been running seem to have no affect.

thanks.

Yeah, just a regular vitamin C tablet like you get everywhere. Nothing special.

I've never had a problem with metals before either, but this year the stains appeared. I guess there must be a cumulative affect.
