+ You can stop aerating -- your TA is low enough.
+ You don't need to keep testing for CC unless you want to do so.
+ You should use the 10ml test sample (1 drop = 0.5 ppm). You don't need the additional accuracy, and your reagents will last longer.

After you've used 10 lbs of dichlor, check your CYA level. Before that time, you should see your FC levels not disappearing during the day.

Looking good!
