    First pool, how long to run the SWG each day?

    Hi!

    We just put our pool up, finished filling yesterday. I want to know how long does everyone run their SWG each day for a pool with about 13,200 gals of water? How about the filter? How long should that be running?

    I've tested the water and here are my results

    FC-4.5
    C-0
    PH-7.2
    TA-90
    CH-60

    I know i need to adjust the PH and TA, could you please help me get these numbers to where they should be! Thanks!

    Enough to where it maintains you an Fc of about 4. Depends on the size of your cell mostly. We recommend one twice the size of your pool gallons a least.

    While you wait for general replies from other members, I thought you might want to see these pages if you haven't already:

    Hope this helps. Have a nice day!

    Basically, I set up my pump at the rpm that would be most efficient to cycle our water which requires about an 11 hour run time for me. Then I adjusted my SWG accordingly, which was 60% for our pool.

    PH is OK and TA is fine. Maintain your PH between 7.2 and 7.8 and let your TA be what it wants to be, it is close enough to in-range.

    What is your CYA level? That determines your target chlorine level on the Chlorine CYA Chart. It will take some experimenting to figure out run time and percentage. I'm at 60% and 8 or 9 hours right now. With 70 CYA and FC target of 9. And of course it is HOT and sunny here right now and we swim every day.

    Don't know the CYA yet, as we just filled the pool yesterday and there was none in the water, but I did add about 5lbs of CYA yesterday, via sock at the return. It was all dissolved by lunch today. So I guess next Tuesday I will know where it's at. But I'm thinking I need to add more cya.

    Poolmath is your friend. At the bottom is a section called Effects of adding chemicals. It says that 80oz will raise CYA 44 in 13, 600 gallons. That is a good CYA number for your location. Assume it is in there and chlorinate accordingly. Chlorine CYA Chart
