    Finally Clear Water - 1st full test results

    FC 11.5
    CC less than .5
    TC ~ 12
    CYA 25
    TA 30
    CH 75
    PH 7.0 (I think this is wrong since I am still at shock level)

    How do they look?

    Should I raise Alkalinity to 100? I was surprised to see this so low. Will baking soda do the trick?

    I will let the sun beat down on the FC and re-take the Ph test to see where it should really be at.

    Did I miss any test?

    I think I am close to being in!

    Welcome Cylon!

    I would raise the Cya, and the pH. I wouldn't worry about TA just now, that pool is very flexible in terms of hardness and TA levels.

    Use Borax or Soda Ash to raise it once the FC comes into range. It won't take long at that Cya, so let it come down first. When it does, check the pH, and use the Pool Math above to see what you need to raise it. Then, go ahead and boost up the Cya a little.

    Shoot for 45-50 at most.

    Bump up your CYA. Retest your pH after your FC gets below 10.
