CC difficult to measure extremely light and cleared up just looking at the reagent.
Not till clear; till NOT-green, even after brushing. Clearing up the dead algae is a job for your filter or vacuum, not chlorine. But you have to kill it first.

Don't worry about CC levels; with algae in the pool, they may fluctuate some. Just concentrate on the FC levels, until all the algae is long gone.
