I need some guidance for my particular situation. My pool (9800 gallons) is completely under a roof, and surrounded on all sides by masonry walls, but it is not indoors, as the walls don't meet the roof by about 3 feet. I also have a vinyl electric pool cover which stays closed unless I'm swimming. So the pool gets very little sun, but some, in the mornings and afternoons (on opposite ends). The pool guys just ran me through their pool school (with such choice hints as a gallon contains 64 ounces -- really), and now it's all up to me.
I forgot to ask if they added CYA during the 2 weeks they managed the start up, but Mr. 64 ounces said I don't need CYA. They left me with a bunch of CYA anyhow and some trichlor pucks, and I'm going to keep using the chlorine pucks until I use them up.
Here are my questions:
1) Do you agree I don't need CYA? If I need to use some, what level should I maintain?
2) I have an ozonator -- in my situation is 2 ppm FC adequate? If I do need CYA -- what level of FC with that?
3) My free chlorine was greater than 5 ppm the first time I measured it but by letting the pucks dissolve completely and not adding more for a few days I got it down to around 1.5 Then I added 2 pucks -- we'll see if that maintains 2 or goes higher.
4) Today's readings: FC 1.5, Total C 2.0, pH 7.8, TA 130.
5) I don't have a test for calcium hardness, but the water in Tucson is practically a solid.
BTW my Tucson tap water pH is btwn 8.0 and 8.2. I know because I keep fish.
Many thanks,
Eva
So far so good -- I want to switch to bleach when I can. I hate the way the pucks outgas so much even with the container closed.

Do you not have a test for CYA? That will be a first step and, yes, you need it. Yours is a unique pool but I would suggest you start with CYA 30 ppm.
