    Sorry, I made an approximation. The proper solution is:

    -log10(10^(-7.4)*10000/10001+10^(-12)*1/10001) = 7.4000434261859642546351588394264

    And this equation is really only good for solutions without buffers so it is not that accurate for a swimming pool but I do believe it is a worst case.
