New owner of new pool, florida gem surface, builders following a startup procedure to protect new surface as in what I have read here in TFP
I have well water-clear water iron at 1 ppm, from well head and at faucet after water softener for hardness, water softene does not remove iron. Tested by county
So they put in sequestering agent on start-up of new build, for the iron. Jack's Magic I believe. I have a new Pentair DE Filter.
Today the store they use tested my pool water, the iron content was now .03% Now that's low, almost none existent.
So my question, did the sequestering agent bind the iron so the DE filter filtered it out, or did the agent just bind the iron molecules together in suspension so they were masked and the test shows low iron, but the iron is still there. Which means as the agent begins to dissipate, the iron will show back up. Or is it really gone?
From what and (all) I have read, you can't filter out ferrous iron.
So what is the correct answer?
