    Added CYA and....

    Added my CYA via the sock method two weeks ago. Tested my level this morning and the black dot is still easily visible at 30.
    According to the Pool Calculator, adding 4lbs. 9oz. (which I did) should have gotten me to a level of 40. I'm thinking it's somewhere around 20.
    There have been a few rain showers that may have added an inch or so to the pool.
    I have not cleaned my filter or anything either.
    I guess I should add more?

    The first thing I would do is check the bottle of stabilizer and make sure it's close to 100% Cyanuric acid. If it's lower than that, then that and the rain might explain why the concentration is lower than expected.

    Re: Added CYA and....

    sounds like it. did you check the concentration of cya? also, make sure you're shaking (turning back and forth) the mixture for 30 seconds before pouring it into the view tube.
    as you know we've had tons of rain this year in this area, and my cya hasn't budged. however I did recently make the mistake of not mixing the container for 30 seconds before pouring it into the tube, and it showed my cya as 50. I was so excited until I did it again the correct way and it was still 70.

    Re: Added CYA and....

    I shook it for 30 secs like the directions indicated.
    The CYA was 99%. It was from Leslie's.
    Should I add more, or give it more time and recheck next week?

    2 weeks is plenty long enough. although I would bring water to leslie's and pinch a penny (or another leslie's, whatever) and get it verified just cause high cya is such a big deal.

    Good idea, I'll have them check it for me and save my reagent, then go from there.
    Thanks!

    Re: Added CYA and....

    Well, Leslie's told me that my CYA was only around 10.
    How can that be?
    I know we have gotten some substantial rain, and my kids do splash, but I didn't think it would lose that much.

    don't know what to tell you. did you add it via skimmer and then clean the cartridge or something?

    Re: Added CYA and....

    No. Cartridge was brand new. It was directly after my Baqua conversion.
    Added it in a sock in the skimmer.
    Don't know. I guess I'll just add more and see what happens.

    Re: Added CYA and....

    All I can tell you is that I no longer buy my CYA from Leslie's due to the exact same problem.

    The last 2 years I have bought it at our local family owned pool store and haven't had any more issues with it not showing up on the test. Might be worth buying it somewhere else.

    I'm glad I'm not the only one that has had this happen.
    I purchased some today from a different store. Adding it now.

    Re: Added CYA and....

    I had similar issue 2 months ago. CYA was at 50 .... wanted to raise it to 70 ..... pool calculator estimated 2 lbs to do the job. waited 1 week ... tested ..... didn't budge. waited another week ..... tested ...... didn't budge. added another 2 lbs (from same CYA container as before) ..... waited 1 week .... BAM! ..... 70!

    can't explain it other than to say the calculator is a "starting point" ...... everyone's pool is different .... use TFP.com and all the good advice here and eventually you will know the ins-and-outs of your pool like the back of your hand!

    Also the CYA test itself is only good to about +/- 10. A range of 50 to 70 is actually still (just) within the test sensitivity.

    Re: Added CYA and....

    Just a quick update:
    I added 3lbs. of Aqua Chem Stabilizer from Wal-Mart 2 days ago. It dissolved a lot faster than the Leslie's brand out of the sock.
    After just 2 days, the pool store (not Leslie's) is telling me that I'm at about 45ppm CYA. I also confirmed this with my test.
    I'm convinced that Leslie's stabilizer is junk, or at least the tub that I picked up.
