Hi, I'm a new pool owner this year. My husband and I bought a 18' x 30' oval pool. We have had it filled for almost a month now and the water is still crystal clear. My parents had pools as I grew up so I know a little about them but not that much. My dad always had trouble with green water and I really, really want to keep mine crystal clear.
Right now my readings are: Hardness 0, FC 6/10, PH 7.2, TA 80, CYA 0. The CYA 0 is what has me bothered. I just got the FC up to 6/10 by shocking it again last night and this morning it checked in from a 1/2 to the 6/10 but previously I had trouble getting it there and Now I need to keep it there.
I understand the CYA is a conditioner, what is this called at the store? Is it Stabalizer? How often will I need to use it? I have heard you do not want to get too much CYA in your pool and I'm so afraid of that. I don't want to mess my water up.
Also the Hardness, I don't really understand what that one is or what that level should be, I heard the lower the better but not 0. Can you suggest to me what I should add and how much.
It is a 13,500 gal pool. I shocked it with powder shock but always leave the chlorine 3" tablets in my strainer basket. I try to keep 2 in there but it still didn't seem to keep the chlorine up at the correct level.
