    PH Testing while Slamming

    I have been slamming my pool for a few days. Still waiting on clear water. Prior to slamming, I lowered my Ph to 7.4. So, because chlorine is high (12), am I correct that I can't get an accurate PH reading with my Taylor Test Kit? If true, how do I know if my PH is okay during the SLAM?

    Thanks!

    You don't. That's why you should be diligent about dosing regularly so it finishes fast and then you can adjust it.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    My results with high FC...I had very high CYA, kept my FC 12-15 for several months (I would let the FC drop to 8-9 for a day to test pH), at my numbers I did not see any measurable difference in what the pH test showed.

    What you call high is not exactly shock level. Check out the pictures in this thread so you can see why we say not to mess with pH during a SLAM. Accurate pH test during shock levels with R-007?

    Yes, you are correct, not intended for during SLAM, but for many with high CYA using higher FC similar to my numbers I believe you still can get a reliable pH test....Thanks for the link, those pictures do tell the story.
