I started Wednesday 4/26 and it was full Friday 4/29. To clarify, this is my first full test. I did a quick FC and CYA test Friday neither registered. Added 2 gallons of 10% chlorinated bleach and 2 lbs of stabilizer then.
I haven't tested the CC yet. I will do that and see where it lands.
I do have a sand filter and I didn't backwash it at start up. I started it up on the filter setting. When I did that it blew a cloud of sand into the pool. There is definitely sand on the pool floor that needs to be vacuumed up. Perhaps it's getting stirred up and the source of the cloudiness?
