Okay to get in and brush?

[DuchessJen]

I was away for a week. I have a little algae bloom starting, due to 0 chlorine. I have added enough chlorine to get to 10ppm FC.

I plan to re-test for CC and then slam. But I'd like to brush the pool before the slam.

My pool brush is hand-held.

At what point is it safe to get into the pool to brush before slamming?

In your other thread you showed a CYA of 50. That makes your SLAM level 20 ppm FC. Safe to swim as long as you can see the bottom of the pool.

No reason to test for CC at this point, just raise your FC to 20 ppm.

Oh! I should have put my current CYA on this thread! I added some water as it had evaporated, which changed my CYA to 40.

That's still a slam point of 16.

Okay. I'll get in and brush the pool, then slam up to 16 until CC Is 0.

until CC Is 0

That is ONE of the indicators of a successful SLAM. You may show a CC of 0 the entire time. But you also must pass a Overnight Chlorine Loss Test and have a crystal clear pool with no debris.
