    Made an error during SLAM - Need advice

    I am in the midst of SLAMing the pool I took a pH test and noticed it was super high. What I didn't realize is that the test is unreliable. The pH was 7.5 when I started. So, I added a bunch of acid to bring it down-which I don't believe was necessary. I expect that I'm somewhere around 7.0-7.2. Am I ok or do I need to counter balance this???

    How much acid did you add? If you plug the before numbers into poolmath and then scroll down to Effects of Adding Chemicals, it will tell you approximately what happened to the pH when you added the acid. If you're at 7 to 7.2, I wouldn't get excited about it. Just fix it when the SLAM is done.

    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.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    If you think you added no more than that, I would agree.
