Okay, I went back and checked the entire thread for CYA specifically. Let me know if I missed something, but the only place I saw where you actually added stabilizer was on July 5 (42 ounces). Is that correct? If so, then that makes sense what you're seeing now on the CYA test because 42 ounces of stabilizer will only increase CYA to about 27 ppm in a pool 4500 gallons. So that would explain why you're seeing a CYA reading of about 30 or so.
So if that's true, then you just need to add more stabilizer in preparation for when you turn-on the SWG. 67 ounces should increase CYA from 27 to 70. NOTE: If you are concerned that your CYA right now is more than 27 (perhaps more like 40 for example), then just change that amount on the calculator to lower the amount of stabilizer added. Does that all make sense? Also, if you did add more stabilizer than what I saw on July 5th, please let me know. Or if you have any other questions, please ask. One thing we don't want to do is go "too high" with CYA. 70 is ideal for now. You can always add more, but you can't lower it (without draining).
