Metal in the water (Fiberglass 35K pool)

It does dissolve before reaching the bottom. It is fine to add sequasol right after the ascorbic acid - and not a problem to add the ascorbic acid after. I would wait a while befor adding more, I think after the water filters for a while it will take the rest of the stain off. You can add more ascorbic acid, but it will just take longer for the pool to hold chlorine. The pool won't hold chlorine till the chlorine eats up all the ascorbic acid that is in the water, that's why I try to use as little as possible. You can even wait till tomorrow to add more if you still have stain. Congrats! you're almost finished!

24 hours later. I have not been home yet, but my father called me and said that water is not as clear as it used to be (foggy?)

Why would it be foggy? Because Chlorine 0? Algae bloom?

How much chlorine can I put in? I know that I have to add it in small amounts, but how small? 1 bottle 3/4 Gal? 2 bottles?

Should I add some Borax? I don't know how much my PH is at this time.

Thanks,
B

The water is cloudy from the metals going back into solution and the sequesterant - it will clear up, don't worry. I would not start chlroine until tomorrow. Then add enough to get you to 1 to 2ppms. You will need a lot of borax, because the ascorbic acid will take your ph way down. Check it, put in a half a box and test 2 hours later. Keep doing that until you get to 7.2. Don't bring your ph higher than 7.2 for now. Keep your filter running 24/7. Test your alkalinity - if it is low you can use baking soda as well.

Checked the water today, it is about 40 hours after Ascorbic Acid was added.

Very cloudy (like milk) Bumped the pump, because pressure was at 35.

Chlorine 0
Ph 7.2 (for some reason it didn't go down as much as I thought it would)
It was at 7.5 when I started adding the Ascorbic Acid

Didn't add any Chlorine yet.

Marie is definitely the expert on this mater in my opinion and you are in excellent hands. Something I do when going through an "ascorbic acid treatment" is add some 60% polyquat algaecide. You can get it for under $20 at the local pool store, Home depot or Lowes. This gives me a little peace of mind and I don't know if it attacks the ascorbic acid or not (Marie?). My treatments seam to work like a charm (thanks once again Marie! )
The cloudy "like milk" water is something I've never personally experienced. It may be normal but just out of curiosity, what is your CH (calcium) level?

My Calcium was at 120-130. Alk was at 80-90

Well that pretty much shoots my "high CH theory" out of the water. Both of those look fine. Maybe it's the metal, scale or gunk. I'd just keep the filter going, bumping as little as possible.
