    New Pool - 1st numbers from TF-100

    I added 4lbs of conditioner yesterday after a CYA test of 0, and will be "creeping up" to the 8lb 9oz needed according to poolmath. I also added the required amount of 8.25% bleach to get the FC to 4.0.

    Here are my numbers from this afternoon

    CYA - not tested, will test again next week
    FC - 3.5 - 4 (I accidentally dropped two drops at once, so I don't know if it would have taken 7 or 8 drops)
    CC - 0
    TC - 3.5 - 4.0
    TA - 30
    PH - 6.8
    Temp - 70 degrees

    This is where I am now - where do I go next? I'm super new to this so I need a bit of hand holding at this point, until I'm comfortable with all of this. Thanks in advance!

    Add baking soda to raise your TA to 60. That will also raise your pH.

    Your 4 FC level seems low. Even though you have to wait to test cya, just assume the amount you added is in there. Then whatever cya you are shooting, use enough bleach to get in high end of range. For example, if you added stabilizer to get pool to 30cya you should be adding enough bleach to get FC to 6 or a little above. Once it drifts down to 4 you need to add again.
