    No CYA?

    I tested and retested multiple times but I never get even a hint of cloudiness when doing the CYA test. My other levels I think are fine.

    Your CYA is zero.

    Have you ever added stabilizer? Have you used pucks or "shock"? There's a good chance your cya level IS zero.

    Re: No CYA?

    A few questions need to be answered.

    How much CYA did you add and how long has it been since you added it to the pool?

    When and what was your last visible reading of CYA?

    What tester are you using?

    Re: No CYA?

    I have the tf 100. We have only owned the pool for under two weeks. previous owner had new liner and SWG installed in may. We have not added anything as of yet. But this morning was the first time that I was able to sit down and really use the test kit. So if it is 0 what do I need to add/do?

    First thing to do is read the Pool School. Then after you are done re-read it. Most if not all of your questions will be answered there. Come back with any questions that you have after reading.

    I'd start by raising your CYA level to 40 and let it sit for a week. Then retest. With a SWG you want your levels around 60.....but do it in baby steps.

    Where do I get stabilizer? We are clueless. Looking at Pool Calculator we need a lot of stabilizer.

    Buford beat me to the punch...

    Make sure to wait a week or so after testing. I always add slightly less than what the calculator says and add a little more after I check my numbers.
