    How are my numbers?

    I'm usually a poster on Pool and Spa Forum but they seem to be having some issues... I see waterbear and chemgeek also contribute their amazing knowledge here

    Kit is a 2106

    pH - 7.5
    TA - 40 - 50 ppm (solution turns grey-ish on the 4th drop then red on the 5th)
    CH - 150 ppm
    Bromine - Typically 4 - 5 ppm
    Borates - 50ppm

    TA is the only thing I'm pretty sure I need to push up a bit to 50. Upon filling TA was 80ppm but I kept working it down with dry acid as my pH was constantly going 8+ when aerating.

    Welcome to TFP!

    Since you are using borates, you can probably leave the TA where it is or raise it to 50 ppm if you want, up to you. Just note that if you use bromine tabs, those are net acidic and will lower TA over time so keep an eye on it and add some baking soda as needed. If you don't use bromine tabs or if most of your bromine comes from oxidizing (either manually added or from an ozonator) the bromide from the bromide bank, then the TA should remain stable.

    Thanks chem geek.

    My only issue now is a slow leak that is having me top up the spa along with re-balancing...
