    Constantly adjusting SWG %

    Still figuring out this whole pool ownership thing... I test for chlorine and pH daily. As the pool is new I'm still having to add MA daily. With my CYA of 70 I'm trying to keep my FC right at 5. Right now it seems to bounce around every few days which means I have to adjust the % on the SWG. Last week the FC got up to 7.5 so I turned down the SWG a bit and last night I was down to 4.5. Is it normal to have to make frequent adjustments to the % on the SWG? Currently my pump is running 8 hours per day and the SWG runs at the same time.

    Re: Constantly adjusting SWG %

    FC is impacted by a variety of factors - water temperature, organics in the pool (bugs, leaves, etc.), amount of sun on the pool, bather load, etc. So, FC will fluctuate some. But, you should be able to get it stable enough so that you only need to do weekly checks.

    So adjusting a few times a week is normal? Seems like the FC creeps up and then I turn down the SWG and it's too low so I have to bump it up again and then it's too high again...

    Re: Constantly adjusting SWG %

    This time of year is tricky with rising temps, increasing sun, more rain cooling the pool, etc. The MOST important number is minimum, Chlorine CYA Chart. You want to make sure FC never drops below minimum or the pool will be u sanitary and algae can grow. It is fine to be above target a few PPM to make sure this doesn't happen. It is safe to swim with FC up to shock level for your CYA.

    Ok thanks. I won't worry so much when it creeps up and just leave it alone. My OCD like to have me mess with things

    Well hopefully the water will be warm enough for me to go in this weekend with said beverage and floatie. Two weeks ago water temp was at 87 which was great but this past weekend it was back down to 77. Way too cold for me. Looking forward to our solar installation next month!

    Yeah, our pool is jumping between 83 and 74. Solar is great! We are 85 water people. Although, I am in 83 water right now and no complaints! But, it is only 88 outside so it is good. Our pool went from 74 on sunday to 83 right now.

    Re: Constantly adjusting SWG %

    You will get a little finer adjustment by adjusting run time, either leave on the lower setting and increase run time by 1 hour or leave it on the higher setting and reduce run time by 1 hour
    test various run times until you get less of a swing.

    Then as the summer comes you'll need to do it all over again as the increased Sun/UV depletes more FC during the day.
