    I just added 20 Mule Borax to my pool a week ago

    I just added 20 Mule Borax to my pool a week ago, so far I love it. My PH seems more stable, my readings are:

    FC- 8.5
    PH- 7.5
    TA 90
    CH- 270
    CYA-80-90

    Borate at 50

    I am a little concern, my CYA was 58 so I added Stabilizer yesterda and it jumped to 90. Sshould I be concern?

    Don't worry about it. You know how to manage an appropriate FC level to ensure you don't get algae. The CYA will slowly drop over time with water dilution and other factors.
