Will Copper affect my attempt to raise pH?

Hey thanks for the information. Actually I forgot, I am using Borax now. I started with 6 lbs. of ash but then switched over. Same result. I'll hold off until the sequestrant arrives.

I might need to use an ascorbic acid treatment to treat these stains. Would you recommend waiting to raise the pH until that's complete too?

Yes, I'd wait on raising the pH unless it's very low (below 7.0). Just note that the ascorbic acid treatment will lower the pH further so when you are ready for that you may want to raise the pH some, but between now and then the pH may rise from normal outgassing of carbon dioxide (unless you are using an acidic source of chlorine such as Trichlor).

actually, if you will vacuum the blue precipitate to waste you will remove some of the copper from your pool so it's actually a good thing.
