I did an AA treatment 2 days ago, and have b n adding liquid chlorine slowly to get chlorine back. After 2 days I have zero free chlorine and TC level is 1. Do I go ahead and shock the pool and not worry about stains coming back? Or is there another option?

Read this. Recommended not to shock.

I read that before I did the treatment. It doesn’t give any guidance as to what I should do to clear up the issue.

After AA Treatment
- Bring up your pH and alkalinity - use Arm and Hammer Washing Soda first; it will raise both pH and alkalinity.
- Make sure you test in between because you don't want your pH to exceed 7.2.
- If your alkalinity is in range, and you still need to raise your pH, use Borax to take it up to no higher than 7.2.
- You can start to bring up your chlorine. You want to do this slowly. It will take a lot of chlorine - preferably using liquid chlorine only at this time, and try to take it up to your minimum chlorine for your cya according to the Chlorine/CYA Chart.
- As you slowly raise the chlorine, watch for stains starting to form.
- If you see stains, ensure the pH is no higher than 7.2, and add more sequestering agent. You should see the stain lift in a couple of hours.
- Do not raise to SLAM FC levels! Do not do a SLAM for at least 2 weeks!
- Make sure you keep your pH low (7.2) for a week or two - it won't be hard because the ascorbic acid and sequestering agent will help it stay low.
- Once your chlorine starts to hold, it means that you have used up the ascorbic acid in the water, and it will be easy to rebalance the pool back to recommended levels.

It recommends to go slow with raising your FC level while keeping an eye out on the pH.
I’ve been doing that. There are no stains reforming. But not only is there no free chlorine but there now is total chlorine and the pool has a little chlorine smell now.

How often have you been adding? Add an amount that should give you at least 2ppm and test after 15 minutes to see if it is registering. Rinse repeat.
It showed chlorine at 15 minutes minutes. Do I keep adding every 15? Or wait longer to test to see if it’s holding?

Check about 30 minutes later to see if it’s still holding. If it is, go up to your level as identified in FC/CYA Levels. If not, only add in small increments until is does hold. You definitely don’t want to overshoot FC into or near SLAM level.
