As I told in "high chlorine" thread I shocked the pool with Cal hypo yesterday. (a turtle visited me so needed to sanitize).
To refresh, I have high CYA (95) so my chlorine is high and is 6.5ppm, not going anywhere though I stopped adding it.
I used three packs of 1lb of 76% of Cal hypo.
I ran the pump and broadcasted the most of it over the deep end, and very little over the shallower part.
While running the pump, after an hour though it was dark, I noticed sediment at the bottom.
I brushed it, ran the pump some more and eventually stopped it.
Today after work I saw a lot of sediment (large white crystals) on the pool floor. All over, especially in creases, but also lots on the flat part and the slopes.
I took the brush and gave the pool a good swish. After an hour or so very little came back, mostly in corners.
Why is it? I never had cal hypo not fully dissolve in my above ground that was nit even that deep.
