You're doing the right thing. :lol: Hang in there. If you drain about 60%, my guess is you'll end up with CYA right around 50-60 and that should be the sweet spot. A little less won't hurt but you don't want more than 60ppm.
Ohm_Boy said:Tabs (trichlor) will add CYA.
Granulated chlorine (dichlor), will add cya.
Calcium hypochlorite (cal-hypo) has no cya, but adds calcium, and it, too, can only be removed by drain/refill or reverse osmosis.
Sodium hypochlorite (liquid chlorine, also bleach) adds neither cya nor calcium. It does add some minor amount of salt as sodium, but this is not troublesome.
Yes. Tabs and powder both add CYA and you still have too much. Your close now, why don't you drain 1/3 of your pool and get your CYA down to 50ppm? Everything will work better for you from here on out if you do.So for my situation where I am struggling with high cya I should be using straight liquid bleah off the grocery store shelf?

That test is for iron....not organics. One of the remaining pucks placed directly on the stain will frequently lighten the stain.....if so, then it is an organic stain.Put a Vitamin C tab on the stain for minute if the the stain goes away then it's organic.

Not necessarily, it is not uncommon for people with iron stains to get no reading on an iron test. The test is only so sensitive, and if you have staining, then most of the iron is usually in the stain, and not in the water.kizerman said:There is no copper or iron in my water so it has to be organic, right?
Find out what he treated it with and post back. As the stain slowly returned, what was your pH? If your pH has been high, that would explain a metal stain.About a month ago I had my pool guy treat it with some type of stain remover that worked almost instantly and cleared the stain from the liner, stairs and all plastic in the pool, however it began to slowly return within days. Any thoughts or ideas here would be greatly appreciated.

Try vitamin C on the stain.
