Jason- I found this thread after searching for metals in the water- we just had a new liner installed and had to refill with water loaded with iron .
You mention that you prefer sequestrants based on HEDP, like ProTeams Metal Magic, and you suggested to lower the PH to 7.2 before using.
As I expect the water fill to reach my skimmers later today, I am ready to throw in a few quarts of the Metal Magic when I get home tonight. However, the directions say the PH should be 7.5 to 7.8... more to the high side and the opposite of what you suggest, 7.2.
I am confused what I should be doing with the PH before I throw in the Metal Magic. PH high or low? Any clarity or advice would be appreciated.
As a side note, I set up a whole house filter on my garden hose before filling. Judging my the 4 completely stained filters I have lying next too it, it definitely helped remove some of the iron, but a ton still made it into the pool. I guess I should have sprung for the 2 micron filter instead of the 5 micron Sad thing is, this is not well water. Nice to know our town gives us clean water to drink/cook/bathe with
