HELP - Ascorbic Acid treatment - I have a problem

[waterbear]

Run the filter...it will work fine that way. I have a cartridge filter so I don't have the option of recirculate and I have used ascorbic acid sucessfully.

BTW, sounds like you need to find a different pool guy!

Thanks.

I finally got a new clamp for the waste hose and it's been zig-zagging all around the pool for over an hour now. I still have stains.

My staining is streaky and lighter but on the one part that was the darkest stain it doesn't look like the ascorbic has touched it

Marie had said there was more that could be done but she didnt' say what.

Did you drop your FC to about 1 ppm and your pH to about 7.0-7.2 before putting in the ascorbic acid? Also, did you put a seqesterant in the water after you put in the ascorbic acid? IF not that could be why some staining still remains. If your pH is high I would try dropping it down and see if that helps. Filter for about 24 hours. If you has high chlorine levels when you put it in you burned some of it up before it got a chance to work on the stains. You might need to get the chlorine and pH down and repeat the treatment in that case.

I dropped my FC down to 0 before starting. My Ph may have been around 7.6 though. I thought the AA would just pull it down... I did put a sequesterant in actually both before and after because I added water before I started and so I added sequesterant with the water, then treated again after I put in the AA.

So, I'm not sure now other than the Ph. Should I check the Ph and drop it now? Do you think that would make a difference at this stage in the game?

I'm going to order another dose of AA. In any case I'm sure i will have to try again.

Drop the pH. If your pool is vinyl don't go below 7.2. If it is plaster or filberglass drop it to about 7.0 and then filter for 24 hours to see if the stains get lighter or disappear. You might also want to test the darkest stains with a vitimin C to see if they lighten. If they do then another dose of ascorbic acid will help. IF they don't post back and we can try some other things.

Thanks for helping me. I am going to go out and test the Ph and lower it if it needs it. My pool is 8500ig fiberglass.

My Ph is 6.8 right now. I've got the pump on recirculate. I will post tomorrow about how the stains are looking.

Thanks,

Waterbear, today I still have stains although they are much lighter and streaky. I still have the pump running on circulate. The Ph is very low. I don't want to do damage. I may have more AA tomorrow. I ordered it last night and if they shipped it today it may come tomorrow because they are only 130 miles from me. Have you ordered from the Chemisty Store in Cayce SC before? Are they fast shippers?

Any advice as to what to do? Can I keep it as is and add more AA tomorrow if it gets here?

Thanks

[gerri]

Well my Ascorbic Acid didn't come today. I am so hoping it gets here tomorrow.

I tested my Ph again and it's creeping up! It is 7.8 now.. should I add some Muriatic Acid to lower it? I'm so scared of handling the MA. I don't know how much for 8500 gallons either.

I am sorry to seem so ignorant.

[gerri]

I got over my fear of Hydrochloric Acid last night and added some. Today Ph was about the same though so I just added a little more.

My AA still didn't come today. I'm not too happy about that. I have the filter running on filter, switched over from recirculate. I also added a touch of bleach. Since it's going to be all weekend it looks like I'm just going to be starting over when the AA finally gets here.

The good news is my TA has dropped down to about 180 now.
