    cloud water when SWG is turned on

    Pool was recently opened. When adding Purity Resist to the raise the alkainity and salt, the water began to foam and turn milky. with in a hour, it cleared. The water is sparkling clean, but when I turn on the SWG, it pours out cloud water. any ideas.

    Sometimes you can get bubbles when the swg is running... maybe that's what you are seeing ?? Tiny bubbles?

    Welcome to TFP!

    The cloudiness is made from a large number of tiny bubbles. The SWG produces hydrogen gas when it is running. Normally this gas forms slightly larger bubbles that rise to the surface and pop and are never easily seen. But when the water conditions are just right very small bubbles will form creating cloudiness just as you describe.

    If you balance all of your levels and wait a day or two the cloudiness will stop. In the mean time, it is purely visual and has no effect on the water or your chemical balance.

    thanks guys.. the water was balanced. this happened a couple of years ago and I had to drain some water & refill, but not sure if we used a different alkainithy product or not. any suggestion on how long this will continue and will it hurt the SWG cel?
    thanks

    This isn't at all common, so we don't have too many examples to go by. But so far it has never lasted more than a couple of days for anyone who has posted on the forum and so far has only happened when the water was cold and the CYA level quite low.

    There is no risk/damage to the SWG. This is all completely normal from it's point of view.
