    K-2006 FC & CC - 0?

    I tested my water again and it looks like everything has stabilized except Chlorine.

    Results:

    FC 0?
    PH 7.4
    TA 100
    CYA 35
    Calcium 130

    I tested FC on the 10ml and it never turned pink no matter how many scoops of the powder in. Does that mean there is no chlorine at all? I cannot test for CC without it turning pink.

    How often do you all test? My pool is in 100% direct sunlight all day long.

    Chlorine is a consumable and will never be stable. You must constantly be adding it to your pool for proper sanitation. CC's test is the same....you can seldom get a reading if you have no chlorine.

    Sounds like you need to get back up in Pool School and read "The ABC's of Pool Water Chemistry".

    My pool is in direct sun all day long as well. I have raised my CYA to 55 to help with the FC loss and I still go through a full bottle of bleach everyday. I was testing my pool everyday until I learned the behavior of my pool....now I test it about every 3 days.

    My CYA is just getting dissolved and we had heavy swimming yesterday so I am expecting none but I am not sure if the FC test should be forced to turn pink with the powder in order to text for CC or is no reading ok. I am getting ready to dump 21oz of soda ash and 228oz of bleach.

    Bring my PH up to 7.6. My kids like to open their eyes under water and I was told low PH can irritate the eyes. My ph was 7.4 and pool school said to add soda ash or borax (I used Borax) to increase mine.

    You have ZERO chlorine if it doesn't turn pink. Add bleach according to poolcalculator to get it up to levels, do it now.

    Essentially you have no sanitizer and are asking for trouble very quickly in my newbie opinion.

    Re: K-2006 FC & CC - 0?

    pH will probably creep up on its own because of your TA reading, but it's in normal range now. FC is more important. Get it up now, or you're asking for trouble.

    Your pH of 7.4 is (was?) perfect.

    Pool calculator is the main reason I added anything. Is a lower end pH ideal? I will test it again today and see where its at. If it needs to be lower I can lower it.

    Glock brings up a very common issue here on the forum. It is VERY easy to assume the pool calculator will fix your pool. It won't.

    Just like the calculator on your desk or in your phone, it is a tool to assist in doing the math but the thinking and understanding has to come from the operator. Glock, not singling you out but rather making an important point. Fixing and maintaining the pool comes from reading Pool School and understanding what the parameters are.

    From Pool School...
    pH indicates how acidic or basic the water is. pH should be tested daily at first. Once you gain experience with your pool, less frequent monitoring may be appropriate, depending on your pool's typical rate of pH change. pH levels between 7.5 and 7.8 are ideal, while levels between 7.2 and 7.8 are acceptable for swimming.

    I can see I need to reread pool school. lol. Is it true that low ph will make the eyes burn or sting? I got that from more than one pool store.

    It is true.....but so could algae too. Keep ph between 7.2 and 7.8, you'll be fine.

    K-2006 FC & CC - 0?

    I understand if your CC is up, you have eye irritation. But with 0 TC, can you have CC?

    ph of 7.4 typically does not bother eyes. Like others have said, let it ride...it will probably go up quickly and you will be adding Muriatic Acid before you know it.

    Not with 0 TC, but you can with 0 FC.
