Just read some other threads and remain confused. I have zero CYA maybe because I've been doing a lot of vac to waste and refilling. I've been pouring 15% chlorine in and having trouble getting/keeping FC up above 10 even using pool calculator.
I haven't run other tests yet other than Ph is 7.0. (Using the Taylor super kit you folks recommend). The pool is finally blue and trying to clear. Vacing to waste not showing trash or green anymore.
--Is the zero CYA causing the problem?
--Is adding chlorine during the day (Hot and full sun) a waste of time?
I'm assuming the plan is to keep pouring chlorine!
Thanks in advance
