Doheny's Metal Out

[PoolDoc]

I have a bottle of Doheny's Metal Out (MAIN INGREDIENT: (Hydroxyethylidene) diphosphonic acid 60%)
I didn't see anywhere that this is ok to use as a sequesterant, but I figured I'd ask since I have a bottle of it.

60% HEDP is the right stuff. Just remember, even HEDP has only a temporary effect on metals. But, be VERY careful not to overdose, especially if you have high calcium levels.
