Day 7: Pool is still crystal clear. Total bleach so far = 56 gals 6%. Pump pressure holding steady. Backwashed yesterday, before adding 3 lbs CYA to reduce chlorine loss.

FC dropped 3.2 ppm, and CC dropped .5 ppm overnight. Should I contine to add bleach in large quantities? It will probably be 2 weeks until I can change the sand.

Here are the overnight readings:

Tue 8pm
7.2 ppm FC
1.0 ppm CC
7.2 pH
200 TA

Wed 7am
4.0 ppm FC
0.5 ppm CC
7.2 pH
0 CYA
