brown stains along rim of pool, vitamin c does not remove stain, idea?

Yes I do know exactly what you mean, but I have a friend that I may try it with. She has some staining on her fiberglass pool. I was going to go over and do the stain treatment with ascorbic acid - maybe I will ask her if it is ok to ty the Proteam to get rid of the stains. I am really interested to see what it would be like, but I don't want to "deliberately" get stains on my pool just to try it either. Maybe chem-geek can look into it to see if metals can fall out as precipitate - I know there are ways to do it with water treatment plants - I was reading about it on the internet - but of course I being chemistry illiterate didn't understand most of it.

Keep us posted of the results if you try the Metal Magic!

I loaded 3 tabs into a sock and it did indeed remove a lot of the stain. So the recommendation is superchlorination to 30ppm? How long do I need to maintain that level? Also, is this likely to cause me to need to backwash? I just put a couple of pounds of cya in and I want to avoid backwashing...

It shouldn't cause you to have to backwash.

I ordered Metal Magic today. I am hoping that it is MAGIC! I must have tons of iron in my water. My stains are starting to creep back and I have tons of sequestering agent in the water, Ph at 7.2 and 3ppm Cl.
