    Pump run time vs. SWG % setting

    So I've found a balance point running the SWG at 40% and the pump 12 hours a day (a seven hour period and a five hour period). FC is 7 to 7.5 every day, pH gently rises from 7.2 to 7.8 over 8-10 days. Pool is crystal clear (thank you TroubleFreePool.com!).

    My question - I want to save electricity running the pump. but I also want to maximize the life of the SWG - so am I better off with longer pump run time, or higher SWG setting? 12 hours at 40%, or 8 hours at 60%, or 6 hours at 80% - all produce 4.8 hours of SWG run time.

    It is exactly the same run time for the SWG as you pointed out and that is all that matters for SWG lifetime.

    So shorten your run time without any hesitation. You wont be sorry.

    I was about to post the same question - but this answers it! I am going to cut back my run time and up the SWG %. Save some $$.

    I totally do not understand why all the manufacturers went with the % generation time settings, it is inconvenient to maintain and you allways have to think abou the SWG when running extra pump hours.
    My SWG is setup at 100% and is cut from the power in normal situation. My control computer turns the power of the SWG on at programmed hours during pump time. With this setup you can control the SWG exactly on the hours you want independent from total pump time.

    If possible, I would go for the such a setup if I was you

    Mine runs when ever the pump runs, which is also when the solar water system is pushing warm water. Which is most of the time.

    I run my SWG at 25%.
