Well, since it is supposed to be a slurry, I added some tap water in it and shaked well. It turned back to a 'slurry/liquid' -which was predominatley smooth. So I used it, it's not a big pool, around 3600 gallons? Supposed to be 3800, but these pools just don't hold what they say imho. It did not seem to have ill affects, water still clear. Will wait a day or two to see if the CYA registers. It had some small particles, but seemed to dissipitate well. I added enough to have around 20 (according to the directions on the back), hopefully I can see something with my cheap drop test... but I doubt it, probably need another small dose at least. I realize that it may not be very strong anymore, I don't know how CYA breaks down. It did not smell like ammonia.

Yes, I know I should have a better test, but this is a just a kiddie pool and I am being as cheap as possible...we only can get around three months a year use out of it...and if you have ready my other posts I have a lot of iron in my water (which is crystal clear now). We generally have a high KID bather load and pool gets full sun- since I can barely get the cover on before someone else wants in! That means A LOT of bleach if you don't have any CYA, even in a tiny pool!

Thanks everyone, its a work in progress! Ill let you all know the rest of the story when I get it!
