    Raise Ph?

    Hi all. I'm wondering if my pH is OK at this level, or do I need to raise it? I have added ph up before, but it seems my ph always stays at this level. The pool math said to add Soda ash, but I'm nervous that I might not have entered it right. Thanks in advance, I have had zero problems since I started my pool because of all of your help.

    It looks good to me , one of tfp moderators will tell you for sure!
    Ph tends to go up on its own.
    Running A fountain will raise it slowly without adding anything.
    Or a air compressor hose will speed it up...
    That's if tfp thinKS you need to raise it.

    Are you using tablets to chlorinate?

    If you find it keeps dropping below 7.2 try raising the TA to 80 and see if that keeps it more stable. Pool math allows you to set target levels. Recommended pH is 7.5 but anywhere between 7.0-7.8 is acceptable for most pools. If you have very high CH levels (over 400ppm) then you should keep pH low to prevent scale formation.
