John, I've seen some of your other posts, and I am inclined to trust most everything you say. Until today I would have agreed with your assesment of the solubility of cya - however, I went back to a pool I had added 5 lbs of cya to 8 days ago and I saw ~ almost all of it still sitting on the bottom. Maybe it's the cold water or lack of a MD in an 8' deep pool (however there are low suction ports at the bottom of the wall and a couple of 'low returns' which should be 'stirring up' the water down there). Not to say you are wrong but, empirically it looks like some pools won't take the cya as quickly as others. No biggie, some pools apparently need more time to absorb the cya
Just wanted other folks who still have the granuals in their pools to know that - they aren't the only ones
