Stain Removal Questions

[Cookieman]

Here is link to AA procedure. It is posted as a sticky by alyad at top of this category. I began trying it July 31. Still working with it. I am not certain I put enough HEDP in it - only dose on bottle. Used Kem Tek Calcium&Metal Eliminator and am using JacksMagicPinkStuff now - both recommended by forum. This time am making sure I am keeping more of the HEDP in the water than before. PoolDoc is the expert, so I continue to read and try to figure out what I might be doing wrong. My stains have come back every time I get my chlorine back to minimum levels 3.0 - 4.0 with PH of 7.2. Good luck.
