    To keep Hayward SAS SWG

    Hello. So I'm considering returning my Hayward basic salt and swim swg. For Circupool SJ-40. I'm on the fence about doing so. The Hayward unit is rated at .98lbs of FC a day. I'm running it at 80% for 9hrs to maintain a FC of 3-5ppm. In 85 degree weather. The 100 degree temps hasn't hit phx AZ just yet.
    The SJ-40 is rated at 1.7lbs of FC a day. With an extra $330 price tag. So should I opt for the bigger unit now that I can return the SAS unit? Or keep my $330 in my pocket and cross my fingers the SAS unit can keep up with the heat . Plus there's no solid number on how long the SAS cells last. One member stated 2 seasons. In a colder climate. SAS cells sell for $170-185. Roughly the cost of Chlorine for a year, maybe.
    its my first pool.
    Many info would be great.

    A,

    In "theory" your Hayward is sized for your pool.

    It may not be a SWCG issue.. Please tell us how much CYA (stabilizer) is in your pool water???

    But, bigger is almost always better when talking SWCG...

    Thanks,

    I'm at 80 CYA . I guess it's going to boil down to running the Hayward SAS at 70% plus during the summer months. Or give in and get a bigger unit.

    A,

    Assuming nothing is eating your chlorine, and it is all lost to the sun, then with a CYA of 80, I'd opt for a bigger cell.

    I would do the OCLT first to confirm that the sun is the only issue...

    A,

    I went back and looked at this again. It appears to me that running 8 hours a day at 80% will generate about 3.1 ppm of FC.. So running 9 hours a day won't make that much difference.

    So it sounds to me like your current SWCG is working about like it should.. We generally say a pool uses 2 to 4 ppm per day...

    Thanks,

    Jim R.
