    Salt Water Pool & Correct start-up #'s


    I am new to owning a pool and to this discussion board. I have already found a large number of wonderful and helpful posts! Thank you!

    Yesterday, I became very confused...
    I did me research, found all the correct pool balancing #'s from the manuals that I received and bought a Taylor K-2005 test kit.

    This is what the manuals told me was ideal:
    Salt ppm: 3200
    Free Chlorine: 1 to 3
    pH: 7.2 to 7.8
    Cyanuric Acid: 80 to 120
    Total Alkalinity: 80 to 120
    Calcium Hardness: 220 to 320

    I tested to pool and here are my numbers:
    Salt ppm: 3100
    Free Chlorine: 5
    pH: 7.0
    Cyanuric Acid: 10
    Total Alkalinity: 30
    Calcium Hardness: 110

    So, I figured my numbers are way off, so I went to a Leslie Pools in my area and had them test the water and point me in the right direction on what I need for my pool. Here are their numbers:

    Salt ppm: 3600
    Free Chlorine: 5
    pH: 7.2
    Cyanuric Acid: 10
    Total Alkalinity: 50
    Calcium Hardness: 100

    What came next was a surprise... They (Leslie Pools) told me everything was great an I didn't need a thing! When I ran the numbers to check the saturation index I was -2.9! Should I be worried or will the pool self balance itself like the guy said.

    Thank you in advanced.

    Welcome to TFP!

    You should take a look at our recommended levels, see the article in Pool School.

    There are several different systems of pool care in the world, but I don't know of any system where you TA is good where it is. I wouldn't raise it very much, but do raise TA to at least 60, perhaps 70. Likewise, for use with a SWG you want your CYA between 70 and 80. Increasing your CH is also recommended, but not as important as the other two.
