Hi all. I am a new owner of a well-water home (previously with swamp that is now a lovely, crystal pool thanks to this forum!)
To date, I've been using a hose filter or my fill water, using jack's magic pink stuff, plus culater, to manage the iron. I tried a semi/mini citric acid treatment to address the steps and some historic iron stains. Worked a little, (a lot on the steps, a little in the bad stains) but i brought the chlorine up too fast and/or did not have enough sequestrate, so iron has precipitated again. Because no one wants me to close the pool, I'm going to wait until fall to do a proper AA treatment.
Today, I discovered that my fill water is indeed connected to the water softener, so it's actually at .5 ppm instead of the 2 ppm native to the well. The pool water itself tests clear, which I presume you would expect with sequestrant (added full dose today and so doing did lighten the stairs.)
I've been reading up on general iron treatment and am learning about greensand.
My question is does anyone know of an "inline" greensand filter made for pools? I've read about the metal trap, but am not sure that would handle the volume the way I want (eg -- always!).
Alternately, has anyone ever added a bt of green sand to a sand filter? Or would that cause a world of unintended trouble?
Thanks for any thoughts or suggestions!
