Split from Ascorbic Treatment--gone bad?? Zea3
I really would like a few more specifics on the use of liquid chlorine to return the pool to "balanced" after using ascorbic acid to remove iron stains. Don't want to do something by mistake and end up with the "iron" precipatating out. My pool looks great without the stains -- really want to keep it that way.
What does it mean to add the chlorine SLOWLY? (e.g. 2 cups or 1qt at a time or a half gallon?) How much is A LOT of chlorine that is usually needed to get the job done. (2gal/4gal/6gal of 10%) What is the earliest I may find the FC holding . . . How likely is it to take a week or more to hold the FC? Will continue to add Polyquat 60% every three days until FC holds.
Here's my situation. I have a 12000gal in ground pool with vinyl liner. Used 1lb ascorbic acid and stains completely disappeared. Added amt. of sequesterant treatment on bottle plus 25% more and have run it first on recirculate and now 24hrs later on filter. PH 7.1, TA 100, FC 0.0. Pool calculator says 23oz to go from 0.0 to 1.5ppm FC. How should I proceed to add liquid chlorine (10%)? How often should I test for FC? Should I keep adding and testing every 30mins until I get to 1.5ppm -- and use that amount to keep FC up. Lot's of specific details about using "ascorbic acid" -- more vague in the on-line directions about "how" to safely get back to operation. Appreciate any concrete advice you can offer. I know that size of pool, organic debris, water temp. can factor in. Just would like some better idea of what is a prudent way to go.
Ascorbic acid and chlorine destroy each other. It is normal to have trouble raising the FC level after an AA treatment. Just keep adding small amounts of chlorine and it will eventually hold. You don't want to add too much chlorine all at once because that can cause the metal stains to reappear.
