Day 10: Pool is crystal clear. Total bleach so far = 65.5 gals 6%. Pump pressure steady. Pool has reached equilibrium: overnight FC drops 1-2 ppm, and CC is unchanged. FC drops to 0 by noon next day. Adding 2 gals 6% about 5pm, and checking levels after dark. Expect to keep this up until the CYA rises and I change the sand in 7-8 days. CYA still below detection point, but seems to be increasing. It's been 4 days since I added 3 lbs, and I'm surprised it hasn't registered yet.
