I'm gonna disagree with WaterMom a bit here.

As long as your chlorine is high AND substantially higher than your CC levels, don't worry about the CC levels -- they will go down. Also, the CC test sometimes shows stuff it really shouldn't, so don't pay to much attention to fine differences.

From my point of view, your chlorine is "stable", when it doesn't change from PM to AM, two days in a row AND when the FC is more than 5x the CC.

Regarding brushing, if you've brushed the WHOLE pool carefully, that's what's needed. But if you have any suspicion of there being piles of stuff on the floor, by all means vacuum it up.

Basically, if
+ your filter is working, and
+ you keep your pH between 7 and 8, and
+ you do NOT add pool store goop, and
+ you keep filtering, chlorinating, and cleaning, then
. . . you will get your pool clean, about as fast as anyone can, without replacing the water or bringing a battery of pumps and DE filters.
