Hi,

Thanks to all that contributed the help on clearing the cloud in my pool. Now I have a staining issue.

I am afraid to try the absorbic acid, but I want to make sure its the correct thing to do.

I am on a well with a softner. I guess I had break through when filling the pool. Pool is clear but seemed dull, and I noticed a ring around the pool, just below the water line.

Read the posts on this site and bought vitamin C tablets. HOLY COW!!! Did not realize how dirty the liner is. It cleared a spot as so bright I had to put on my sun glasses.

OK Here what I am going to do.

1. Buy absorbic acid. (saw links here for $22 for 2 lbs)
2. wait for chlorine to get to 0
3. add polyquat per instructions. ($24 bucks ugg. But better to get what I had before)
4. Get PH down to 6.8. ( How critical is this? My PH is always 7.2 and never really moves)
5. add 1/2 lb acid around walls and circ for 24 hours
6. add some metal something. (This I am not sure. I read to add 1 1/2 more then stated. How critical is this. Will the iron just filter out?)
7.Add chlorine slowly, but do this possibly with triclor pucks in the skimmer. This will alow the iron to filter. keep chlorine at 2ppm?
8. After a week or two bring all to normal levels. And dont shock buring this time.
9.Should I use my sand filter during this process, or the cart filter. The cart is new.

Please add anything if its wrong. I want a bright liner again, and I think all that shocking to get the pool clear did it. I never had a staining issue before.
