When to add sequestrant - after ascorbic acid treatment?

[Jen_with_one_n]

How quickly after ascorbic acid treatment should I add the sequestrant? Does it have to be immediately? Or can it be a few days later? (Wondering if I should go to the local pool store to buy it or order on Amazon) I plan to do the AA treatment today.
Thanks!

Does it have to be immediately?

Yes. As soon as you begin to lower the FC level and/or add the AA (which will eat-up the FC) add the Poly 60 in hopes of avoiding algae. If you get algae, all bets are off and a SLAM Process would be required which could defeat the purpose of removing the stains.

I was asking about the sequestrant (like jacks magic pink stuff), not algaecide.

Gotcha. You probably already saw it - step 9 in the AA instructions

I did see that. I’m wondering if I need to add it within minutes or hours of when the stain is gone. It just says “after the stain is lifted”.
Or maybe better asked this way, how long can I wait to add it before it’s been too long? Is there any downside if I wait a day or two?

I would add it right away. Since the iron is still suspended in the same water, it can react as soon as you start increasing the FC again. That's another reason the instructions say to increase the FC slowly and watch for stains that ay try to return. The sequestrant helps with that regard.
