Thread: My pool numbers, need help!

    My pool numbers, need help!

    I tested my pool, the numbers are as below,

    Free Chlorine - Couldn't get it, I guess this means Zero
    Combined Chlorine - almost zero
    PH - 7.2
    Total Alk 70
    Clacium Hardness 250
    Cyanuric Acid <30

    And i can find a little algae in the pool. I used the pool calculator, but don't very clear totally how much chemistry I need to input to my pool. Thank you for your help

    Welcome to the forum.

    What method of testing did you use to arrive at your pool chemistry numbers?

    Also, please include some information about your pool. Many thanks.

    You will find a wealth of information in Pool School.

    In the meantime, since you mentioned that you have algae, please read this article: pool-school/defeating_algae

    How are you chlorinating? If your chlorine level is actually zero, you should raise it consistant with your CYA level. A better quality test kit may be of benefit too, such as from http://tftestkits.net/splash-page.html

    Don't worry, you will have a sparkling pool in no time.

    Oh, where are you located, material of pool, and filter type?

    The test kit you have should be fine - if its the re-branded Leslie's version of the Taylor K-2006.

    How are you adding chlorine to the pool? It needs to be added every day, via tablets or liquid...

    Raise your CYA to at least 50. Earlier in the spring my CYA was 20 and I was losing a lot of chlorine to the sun.

    Good morning, Selena,

    While you're reading through Pool School, get some chlorine in your pool ASAP. This evening...no later...sooner is even better!

    Since you don't know dosages just yet, please put in one large jug of Clorox each evening for the next few days while you learn about the chemistry and get some other stuff done.

    Secondly, you need CYA in your pool. Four lbs to start but plan on using about 8 lbs (it usually comes in four pound increments.

    Post back.
