Day 4: Pool is crystal clear. Toal bleach so far = 33.1 gals 6%. Pump pressure unchanged. I think I'll call it done, and replace the sand today.

Chlorine disappears quickly due to low CYA. Leslie's recommends their Instant Conditioner, instead of cyanuric acid. It looks like the big advantage is it disolves quickly. Any comments on this product?

Current readings:
2.5 ppm FC
1.5 ppm CC
7.2 pH
0 ppm CYA

Thanks for all your help!!!
