    Retested the water:
    FC 5 ppm (no change)
    CC 0 ppm (no change)
    pH 7.4
    TA 120 ppm (before stabilizer correction) (no change)
    TA 97 ppm (after stabilizer correction) (no change)
    CH 220 ppm (no change)
    CYA 70 ppm (no change)
    Salt 3600 ppm (once again using the display on the Aqualogic. The pool temp has come down some but since the aqualogic acutally uses conductivity to determine the salt readout the addition of the tetraborates might have caused this 100 ppm increase. I will check a sample with the salt meter at work)
    Borates about 50 ppm, perhaps slightly higher (measured with AquaCheck borate test strip) (The dilution seens to have worked!)

    I am a bit surprised that I see no increase in TA but then again I started the process with the pH at 7.6 and it is now at 7.4 so that might account for it.

    Now it's going to be just monitoring the pH and see if there is any difference in the speed and amount of pH rise over time and the amount of acid needed to correct it. I will keep you posted.
