    Question about CC

    I have been having a little trouble with my SWG settings, and I have addressed those issues in that forum. My FC is at 7.5 this afternoon, and my CC is at 0.5, This morning my CC showed 0, crystal clear water. Yesterday I did two chlorine tests, and one time CC was 0 and the other time it was 0.5. What am I doing wrong, or am I just over thinking this. BTW my CYA is 70.

    Don't beat yourself up. As long as the CC doesn't exceed .5 or really spike on you, you should be fine. Assuming there were no testing irregularities, your water may just be working to process some stuff via oxidation, and you just happened to grab a sample at that particular time. Good thing is you know what to look for.

    The rule of thumb is to treat .5 CC as if it were ZERO.

    Re: Question about CC

    I am in the process of doing a OCLT test, and my FC was at 4, and CC was 1., or 1.5 because I took two tests. FC was at 7.5 this afternoon. I am at a complete loss, as I have tested and retested since I opened a month ago, and my numbers have been so good. I could go on about how many times I have brushed, and run the manual and robot but I wont.

    Do I wait until morning and see what my numbers are, or do I go ahead and dump the gallon and half of bleach in tonight. I don't have enough for a full SLAM on hand, but maybe enough to get started?

    I guess I will need to use the manual vacuum for this, not the robot?

    Last but not least.........I AM STUNNED!!!

    Re: Question about CC

    Good morning. I didn't see your last post until this morning. Hopefully your OCLT went fine. If not, you probably know what needs to be done from here. If you did pass but your CCs still seem elevated, please post a full set of results and we'll see what we can do.

    Re: Question about CC

    OK, I must be in the twilight zone! I lost sleep over this last night......HA! I am going to post the numbers now, and I promise I was not drinking last night either, at least not until the test was over.

    Todays numbers

    FC: 7
    CC: 0.5
    PH: 7.5
    TA: 70
    CH: 75
    CYA: 70 (Tested yesterday)
    Salt: 3300
    Water temp: 71

    I have no idea what is going on. I hold my reagents vertical and watch the drops carefully so they are the same size. I am at a loss to explain last nights numbers. Pool looks as good as it ever has, you can easily count the holes in the main drains. Good thing I didn't start dumping in the bleach I had on hand last night!!!

    Those numbers look very good. You're ready to start your weekend. It's Happy Hour somewhere in this world.

    Re: Question about CC

    I'm sorry if I'm beating a dead horse here. This really has me concerned. Is it possible that my test cylinders were contaminated? I rinse after every use, and dry them with a paper towel before returning them to the box. Should I clean them somehow? If so.......with what?

    Re: Question about CC

    They are fairly new right? Probably fine. But whenever those tubes look to appear hazy, coated, or dirty, simply clean with some bleach. Let it sit for a couple minutes and that should do the trick to break-up any residue.

    Six months old and look brand new. I hope I just made a mistake last night, but I sure don't know what it would have been.

    Re: Question about CC

    Trust this morning's test. It's the latest reading and you were probably sober at the time. You're getting to know your pool very well ... the clarity, how much FC it uses, and how much chemicals you typically put in. But from time-to-time, something will change and you'll see it. That's what TFP is all about - you being in control. For now, it doesn't appear you have any worries. When/if you do, you'll know it right away and know from your TFP learning what to do.
