I am in day two of "start up".. Been dumping the bleach in.. Have had CL up to near 20ppm,.. but can't seem to leep it there. I understand it's going to go up and down.. but is 18ppm down to 3ppm overnight reasonable?

While the ppm was down this morning.. I checked the PH.. it's about 7.8. I can't check stabalizer.. I ran out of R-0013. I would guess its not too high.. I have never had high stabalizer counts.. and usually each sprng its low. I do a lot of back washing, etc

The water color has turned from a med/dark green to chalky white after 24 hrs.

should I be overly concerned about the drastic up and down CL readings? It seems in years past it wasn't this hard to keep the reading high while starting up.
