    I am going to try the ascorbic acid method for stain removal Ben last edited this week. Once you add the sequestering agent (I also did not see the amount to add per 10K gal), how long before you can begin to add chlorine back. Maybe I missed something. Everything else in procedure seemed clear. Wanted to get a feel of how long before swimming can resume -chlorine at minimum per best guess chart. Going to order the materials this weekend from Amazon. Thanks for all the help.

    You can add the sequestering agent per the directions on the bottle. You can swim as sonn as your pool starts to hold chlorine. The ascorbic acid will not hurt you, you just want your water to be sanitized. Sometimes if you have a high calcium level, you water may get cloudy- it is just precipitating out of the water and will clear up with bleach. Sometimes it takes a lot of bleach until it eats up the ascorbic acid. Just make sure while adding bleach you don't take it to shock levels - let us know if you have any questions,
