10,000 gallon inground pool, vinyl liner, use bleach
Background: Our well water is filled with metals and I always use "Metal Free" to sequester the metals at the beginning of the season with a few smaller doses through the year if I have to add water. If I don't use a sequester agent, the water will turn green/brown instantly when I shock.
-Our pool is closed. Our bottom drain is leaking which is making me put 1 inch of water in a week now.
-Problem: I haven't added any sequester agent and now it looks like my liner is turning brown. (Stupid on my part. I just didn't think the chlorine level was high enough to cause a problem.) I did just add a bunch of the sequester agent.
-Question: Can I just let it go and treat the stained liner with ascorbic acid powder at the beginning of the year. (I think yes.) OR, should I drop in some ascorbic acid now and let it go. (My water is drained below the jets and I have no way to circulate the water.) Will the ascorbic acid hurt the liner by sitting on it for 5 more months?
Thanks for any help. I use to be on the old poolforum site years ago when I converted from baquacil to bleach and I recognize a few name from there.
