It did cloud the pool a little after this wash. I might not have noticed it earlier, except I'd run the filter 24/7 for three days doing the alkalinity adjustment thing, and the water -was- super clear before I opened the sand filter and used the garden hose on it. No matter, it's already starting to clear again.

Down to 100-110ppm from 230ppm after (now) nearly four days of this. I've just been playing with some PVC fittings to convert one of the eyeball returns to a fountain, ten feet in the air and hit the other side of the pool with the water. LOL, the kids like it.
