    Yes, it appears to be...but what are using to get those numbers?

    You need to SLAM your pool. Link in my signature. What are these results from? It would be best for you to get one of the recommended test kits, also in my signature.

    Re: Need help lowering CC..

    Those are pool stores numbers.. In the process of buying a test kit.

    Is it safe for the kids to swim?

    Thanks for the help

    Re: Need help lowering CC..

    If those number are correct (pool store results can be unreliable), personally I wouldn't allow swimmers since that high of CC (depending on the type) can be very irritating.

    Many of us have the tf-100 since it is the best value.

    Re: Need help lowering CC..

    Last Thursday I did a full drain acid wash.. So I am in the process of stabilizing the pool. Did a shock and put 6 pucks.. 3 in each skimmer . Also added jacks magenta for staining..

    Hope this helps..

    Re: Need help lowering CC..

    Assuming those numbers are correct, a quick "shock" and pucks in the skimmer are not going to solve the problem (and the general opinion on the forum is that pucks in the skimmer are never an answer). The SLAM process is designed to bring your FC level up to shock levels and to keep it there until the problem is taken care of. It is nearly impossible to do properly without an FAS-DPD test which is only available in a few test kits, 2 of which we recommend (see link in my signature). You need to know your CYA for sure (pool stores are rarely correct on these tests) and will need plenty of chlorine. Assuming the "shock" you use is powdered calcium-hypochlorine you can potentially use it, but our recommendation is liquid chlorine/plain bleach. Never use powdered dichlor or trichlor to do a SLAM.

    It is not unsafe necessarily to swim, but CC that high will almost certainly be irritating to swim in. I personally would fix the problem first.

    Re: Need help lowering CC..

    As has been suggested here and in your other threads...you need a test kit to move forward.

    I was going to combine you threads, but I decided against it for now.


    Please keep all you posts in this thread from now on until you finish this problem.

    Re: Need help lowering CC..

    I understand I need a test kit.. I'm in the process..

    Since I have swg can I super chlorinate (shock) instead of slam??

    No, it won't fix the problem and is not healthy for the cell. You need to bring it quickly to SLAM level by adding liquid chlorine and keep it there until you meet the 3 criteria: Clear water, Less than 0.5 CC, and Pass an OCLT. It may all sound like overkill if you have never done it, but the process was created through a lot of work and is what it takes to completely eliminate organics and CC from your pool.

    Re: Need help lowering CC..

    No, not really. The HTH only measures TC (Total Chlorine) and it is limited to 5 ppm.

    If you are going to SLAM the pool and you have any CYA (like from those pucks) you are going to have a shock level target of something near 12-13 FC, based on your CYA. IF you have already ordered your TF and you are NOT swimming, you could add enough bleach to your pool to get to 12 and use your HTH to see that you stay above 5PPM at all times. You could then add an amount to estimate the difference between your measured and 12FC target. I know we are guessing but you have at least some idea where you are at. I don't trust the pool store numbers out of a computer.

    Re: Need help lowering CC..

    Have you added cyanuric acid since the refill?

    I wouldn't trust that cc reading. Have you used non chlorine shock?

    CYA is a stabilizer, not a shock product.

    What chemicals have you added to the pool. If you get the actual chemical names that would be great!
