Is it true that the stabilizers in the water rest at the top? I have been draining down to the skimmer, refilling, then rest 6-8 hours and repeat (I was not sure how much time to give the stabilizers to settle at the top after refilling). I have done this three times now. I am not sure I trust my testing abilities, but I think I have dropped the CYA 15ppm to about 80ppm.

I went and bought generic 8.25% liquid bleach and think it is probably time to add as my FC level is now down to 6, I am trying to keep it high while we are in the process of lowering CYA. I was wondering about the procedure of adding bleach. Do I need to dilute before adding, and do I add it straight to the skimmer or poor over the pool surface?
