OK.

That's not so good.

Do you have exact brands and label names of the "Metal ...." products? Many of those products contain HEDP. Typically, a bottle will be an appropriate dose for a full size 20x40. If that's the case, you may have added a 7x overdose of HEDP to your pool . . . TWICE.

HEDP, in overdose conditions, can precipitate calcium phosphonate as an essentially un-filterable colloidal (really, really small particle) suspension. I did this once, to a 240,000 gallon pool, turning it into a pool filled with 'milk'. It took us two weeks with a massive vacuum DE filter to clean it up.

And, that's just the "Metal . . ." stuff.

Pool Stain Treat is a United Chemical product. Their products notoriously work like black magic: impressive results up front, with a horrible price at the end. They put sodium bromide in almost everything. In Pool Stain Treat, it would lower the oxidation potential of the sanitizer (by changing it to bromine) thus tending to reduce the staining. But bromide INSTANTLY changes your pool to stabilized bromine. They also like oxalic acid. But besides its toxicity (probably not a major risk, because of the way it's applied), oxalic acid has its own chlorine demand. I don't know how large the demand is (Chem Geek may), but it exists.

Honestly, at this point, I have no idea what's in your pool, or what it's doing.

If you have an above ground pool, the most straight forward thing would be to drain and refill. At least that way, we'd be working with a couple of known issues, rather than half a dozen unknown ones.

If you don't drain, we may find you can clean things up in a few days. Or, it may not clear all summer long.

Good luck,
