I think I need to do a bucket test to figure what this pool needs. Right now I feel like I am feeding a bottomless pit.

6:45 am the FC was 1.8 CC was 0. Added 1.5 gal bleach and checked again at 830. FC was .8 and CC was over 2. Could this rapid burn off be from the sun? I added a dose to get me to 10 ppm and in under 2 hours it was lower than when I started?

Will adding CYA at this point help with any chlorine demand? I wonder if getting the FC levels to hold longer will help.
