Metal in the water (Fiberglass 35K pool)

[blk133]

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.

I got a DE filter EC-75, I bumped 5 times slow down and quick up. Why bumping as little as possib.?

[DavidD]

Because bumping causes the DE and "stuff" to loosen up and it may very well cause some of the "stuff" ( which is hopefully the metal in your case) to go back into the pool. Now this is only my theory but seems logical?
A couple of days after I do "the treatment", I always change the DE and I also have the EC-75, which I love by the way. The only time I change DE is when doing the "ascorbic treatment", which is usually a couple of times a year. I buy a 21 lb box of DE before opening and it last all season as the filter holds 7 lbs.

Adding polyquat is a good idea, especially if you live in a hot climate. I don't usually add any, and I haven't gotten any algae after a treatment. The polyquat won't hurt the treatment at all. The first time I did a treatment my water was like milk also. I had a lot of stain - the whole pool was stained. The water will clear up, but if you want to, you can try flock. When I had the very milky water, on the 4th day I used flock in my pool. It cleared up the water. I put it in and waited 24 hours, then I vacuumed to waste. It did a great job of clearing my water, and I didn't get any stain back. I did add more sequesterant after I used fill water (from vacuuming to waste). If the stain is all gone, then doing the flock now won't hurt. You don't want to do it if you still need to get stain off. I can understand that you want to have the pool ready to swim in - and no one wants to swim in a cloudy pool.

Don't have polyquat yet. Pool still looks like milk. Pump's pressure is at 35 (normal 22) don't know if I should let it run overnight.

Added a bottle of chlorine 96oz and after about two hours added one more.


What do you guys think? Should I let it run overnight? Pump has been running for about 54 hours.

Thanks,
