I'm planning an ascorbic acid treatment and a drain out.

[Chuckiechan]

I plan to do the AA treatment on my plaster pool. Do I let it do its thing for 24 hours, then begin pumping out the pool. Do I still need a sequestering agent?
Also, what is the PH protocol? Do I add the AA then bring it back to neutral? Or is the relatively short time between the AA treatment and draining make that irrelevant.

Thanks in advance.

The link below should walk you through the process. If you still have some questions, just let us know. Good luck!

If you are going to drain right away, you might get by without the sequestrant, but then again if the drain takes longer than you think it might be cheap insurance that the iron doesn’t end up back in the water. I wouldn’t worry about pH unless things hang and your numbers are way out.

Can you recommend a sequestration agent?
Also instead of using 20 mule team for borates, are there easy other options? (Salt pool)

Boric Acid from Dudadiesel. Get the granular.

Will I need to add acid like with twenty mule team?
and how much to start with for 14,000 gallons?

No.

and how much to start with for 14,000 gallons?

Use PoolMath, Target 50 ppm Borates

BTW, The pool app did say to add acid. I used Boric acid as my choice, rathe than the tetraborate pentahydrate.

What is the benefit over 20 mule team? I'm thinking it may not be worth the hassle if it a wash. I'm in the "gathering phase" of supplies for an ascorbic acid soak, pump out, repair, refill back to SWG specs.

BTW, thanks for helping here.

Not sure what you mean. If you use Boric Acid, you will lower your pH a very small amount.

If you decide to go a sequestrant, Metal Magic and Jack's Purple are the two most popular I have seen mentioned here. But I kinda agree with the others... if you are going to drain anyway, why bother. As long as you keep the pH the same during the draining process it should stay in soln.

I think I got it from here.

thanks for all your help!
