    Am I close to being out of this mess with a CC of 1?? I have used about 25# of 3" pucks and too many gal of beach to even count. I have bought all of the local stores out of borax and big bottles of bleach. (They all look at me funny when I come to the store daily for 2 boxes of Borax and 4 bottles of bleach)

    Today I had a low FC of .5 and CC of 1 but I put in 5 gal of bleach and now have a FC of 6 and CC of 1.

    Recently I have added at least 10 boxes of Borax, but my pH still is at 7-7.2. Water still cloudy.

    Thanks for the help.

    The way to tell is to look and see what happens overnight. If you have 6 ppm at 7 or 8 PM your time, and still have at least 5 ppm tomorrow morning . . . you are probably close to done.

    Still not there. FC still dropping to 2-3 at times. CC still at 1.5 and pH at 7.0 no matter how much borax I throw at it.

    Please Help....

    Am I doing something wrong???
    I have continued to have 3" pucks in the skimmer and have gone through a 50# bucket, I buy at least 3 gal of bleach and add every night and I still have FC from 1-4 but CC is still 1.5 to 2.0 but what is real concerning to me is that I am doing something wrong is the pH.... I add box after box of Borax and still my pH is going down to 6.8.

    Is there any advantage to "washing soda" over borax?
    The only reason is that the Washing soda is cheaper where I live. I have only added Borax but I have added probably added at least 12-15 boxes since this started. (I just don't want to screw it up by adding too much, or maybe that is not possible)

    Also I add the Borax through the skimmer, is there a better way???

    (I don't know if this is an issue but I have a Poplar and Oak tree overhanging the pool as well as arborvitae shrubs about 10' from the pool. The Poplar trees have been releasing a long skinny "thing" when their leaves come out and collect in my skimmer, I dont know if that will effect the pH.)

    My water is now clear without any real odor.

    Thanks for your help

    This is a long thread. So that I don't have to reread 40-some posts, can you remind us what your CYA level is, when was the last time you added any and how much did you add, and what kind of test kit are you using.

    I am using a Taylor 2006 at your recommendation. My CYA was 0 when I started but I did add 4lb of stabilizer a week and a half ago which should be enough to get to 20 ppm, but have not tested it because I only have the basic start up re agents for the Taylor which has only enough for a few tests. I was going to wait until I got my CC to 0 first but I just cant seem to get there.

    The trichlor pucks are acidic and are driving your pH down. Continue to work on bringing it up. Washing soda will raise pH and alk whereas Borax mainly affects pH. Adding it slowly through the skimmer while the pump is running is the correct way to do it.

    What is your chlorine reading in the evenings when you test (but before you add bleach)? How much chlorine are you losing overnight?

    Go ahead and test the CYA level and report it. You can always buy refills on the CYA testing reagent.

    My CL readings at night are between 1-3ppm, I then add 3-5 gal of bleach, then it is then 5-7 on average with CC 1.5.

    My pH was 6.8 today and TA was 140 the last I checked. So it sounds like I would be better to stay with Borax so I dont get my TA any higher. My jets are aimed at the surface to raise the pH but that has not seemed to work for me.

    Is there anything wrong with adding bleach through the skimmer? I normally add at the return jet in the deep end.

    Oh, do the 3" pucks from Sams club raise CYA?

    Thanks,

    Mike

    Yes the trichlor puck raise CYA. They also drop pH.

    Ok I went home for lunch and took all new measurements:

    I am not sure if I did the CYA test right. I went until I could not even see a hint of black and got 70 but it started to dissapear at 100. This is shock because I had 0 to start and only added enough stabilizer (4lbs) to get to 20. I have gone through a 50lb bucket of pucks. I screwed up I guess by adding any at all since I was still adding chlorine by the 3" tabs. I just didnt realize they add that much that quick.

    Here are my other values:
    pH 6.8
    TA 140
    CYA 70 (I also checked this with test strips that I had and got the 30-50 range but I do not know how accurate those are)
    FC 3
    CC 3

    Please help!!!
    The 3 CC is frustrating since I thought I was out of this mess.
