Daytime chlorine loss doesn't tell you very much, other than there being some chance that CYA is a little lower than you think, or you live somewhere extra sunny, or there were several people swimming.

solar cover was washed ( soft scrubbed with chlorine solution ) last fall before being stored, in anticipation of spring conversion to chlorine.

weather has been very sunny and hot (hi 80's) last few days. will get some readings from pool supply and see if they are in line with the numbers i'm getting. pool is crystal clear. not adding anything tonite and giving the pump a nite off. will check chemistry (CYA) tomorrow a.m. and then compare with pool store.
Mission Accomplished.?????

You're done when...
1. Your water is crystal clear.
2. You lose less than 1.0 FC during the FC overnight loss test
3. Your CC's test is .5 or less

quick question...i've been adding the liquid chlorine ( both 12% and/or 6% thru the skimmer with filter running. any problem with that, or should the bleach be added directly into the pool??
and is a 1 to 2 FC ppm loss during a sunny day unusual?? i'm trying to keep the levels at 4-5 ppm with the CYA at 50...the numbers":
pH...7.5
TA...130
CC...0
FC...2
CYA.45/50

1 to 2 ppm chlorine loss over the course of a sunny day is normal, even a little lower than average.

liquid bleach...into pool or skimmer?? or either one??
thanx again for all the help.

Liquid chlorine should be added to the pool, over a return, when the pump is running. Adding chlorine to the skimmer will result in very high chlorine concentrations in the pump and filter. This is not good in the long term.
