    Interesting. Can anyone explain why reversing the polarity does this, and if it's a good idea?

    7th grade science class. Separating hydrogen and oxygen from water........

    Yes what he did in the video works to descale the electrodes. But, if those electrodes are made of different metals, you should switch it back as soon as it's done.

    You might, every second or third tome go ahead and acid wash after. There will be some scale remaining each time.

    I would be real interested to see what his test results say. He seems to develop scale pretty quickly.

    Our circupool si-45s are self cleaning, so I will would guess that's the same process automatically going on with ours. Only we can't see it happening.

    Re: what do you think about this???

    Guessing here, but I'd bet the better brands of SWG aren't sending straight DC to the electrodes. Probably PWM (pulse width modulation) and switching polarity after a set amount of time.

    They still need cleaning, because even this will still collect some persistent scale. Just not as often as one that sends DC.

    The Hayward SWG also automatically switch polarity every time it starts to generate.

    My Intellichlor switches polarity for self cleaning, I believe the manual says every 4 hours. Even so, the book also says to remove and clean every 3 months I think it is.

    Re: what do you think about this???

    I think "self cleaning" is one of those features that is working its way down the product lines for SWG's even the little cheap Saltron Mini have in my hot tub has automatic polarity reversal self cleaning.
