OK, I've slowly been increasing the "guestimate" on the size of my pool (gallons). Yesterday my FC was 2. based on the pool math calculator, I used 6500g, FC 2, target 5, using 8.25 bleach. Calculator said to add 39oz.
Now, I am in SC, temps in the upper 80's, very humid. How much FC should burn off in a give 24 hr period. CC is virtually 0.
