    Quick Question on Slamming

    I've been following the instructions for SLAM-ing my pool since Friday 6/12. The pool has gone from swamp green color to an Aqua Blue. When I started the CYA was very high, close to 80 with Zero FC, I retested the CYA after adding much chlorine the last few days, and my CYA is now down below 30. My question, is the CYA test valid during SLAM-ing, or is it skewed like the PH test? If it is valid, should I also concentrate on getting my CYA back up to 40?

    Does high FC effect an accurate CYA reading?

    Nice reference thread for you. Enjoy!

    Does the cloudiness of a pre-SLAM pool contribute to a higher than normal CYA reading? Try putting just plain pool water in tube and see what you see?

    Re: Quick Question on Slamming

    Thank you for the link to the post. If I am reading that correctly, it just states that I made an error testing my CYA level. That's fine if I did, but still leads me back to my original question. Can I measure and/or adjust CYA during the SLAM-ing process?
