Iron in water source

BigDave: Glad you're here

Yes, the HEDP is to keep the iron in solution and it sounds like that's what stcohen is describing as happening.
Do you think he needs to add more?

I saw Ben's references (quoted below) about chlorine.

Clean the skimmer basket, then add 1 - 2 cal hypo tabs in to the skimmer... Don't add more than 1/2 pound per day.

The problem you have is that adding chlorine to a pool full of iron tends to make staining inevitable. Ideally, you need to remove the iron BEFORE you begin chlorinating. BUT, you can't let the pool become a slime pit during this period.

All I found about pH is below. I'm wondering about raising pH to 7.8...:

...adjust your pH to near 7.0 . . . but NOT lower.
