After AA treatment

[cledee]

I did an AA treatment on Sunday and have balanced my water.

My question is when do I start adding additional sequestrant to the water. Do I start adding weekly on Sunday May 22nd or should I wait an additional week, before starting to add more?

Each manufacture may have their own recommendation, but it's just that - a recommendation. Each pool's chemistry is different. Current FC, pH, iron content, etc all play a part in how likely iron will try to precipitate out of solution and stain. I would say start with a relatively short schedule, keep your water balanced, and go from there. Increase intervals by a couple days or so and look to see if you find new staining. If you see new stains, that's when you know you've gone too far without additions.
