Waterbear...pump run time has been constant since mid summer. I intended to put that in my 'facts' but neglected to.

My pool has been very quick to change ph (upwards). I've always attributed that to the SWG. I usually need to add about a pint a day, and have needed to do so since startup two years ago. Now in the summer, when the SWG is turned up because of more chlorine eaten up by sun, I have to add more muriatic.

Short and long of it is highly unusual for me to have a ph of anything other than between 7.2 and 7.5.

But don't get me wrong. I am pretty darn happy to not have nearly as much of deposit to clean up. And the kicker is that my SWG cell is likely to last a fair amount longer when it is turned off 4-5 months per year.
