Confirmed dichlor is 99%.

I've added a few cups of that as needed and also added a cup or two of Borax for my pH. Pool water is getting better. You can see the bottom across the whole pool but it's not crystal clear yet.

My question now is what level should I be shooting for on CYA? Last I checked it had gotten up to 35 and does seem to be holding a bit better. I get full sun all day in SC.
