I filled my 20x48 ag pool on the 21, and I have added a total 3 16 oz metal and stain from hth at Wally world, my iron is soooo bad from well, I saw that some one said try a paper towel in skimmer basket , well a roll later that was getting old, I have now gone to a 5 gal bucket of fresh water and few old wash clothes,pretty raggedy so I can keep good flow going , and a few of my type of pool filter cartridges , ( intex stuff ) but I have gone out hourly and swapped out wash clothes and filters, a very smooth fast process, and it's nasty nasty, but I think I am getting a grasp, so that I an gain control on my FC and build up cya , Since I'm still in my shocking process
Its been a nightmare, I think if or when I have to drain I will plan on buying water somehow, bottle water woulda been cheaper .... But this wash cloth and filter deal is hopefully a decent plan to rid the well water iron ..
Good luck !!!!
