A Theory About Rising pH in SWG Pools

[fofa]

All my returns, 1 - do not bubble, at least that I can tell, 2 - are pointed down because my cleaner instructions said to do that. I still take 3 pints (30K gallon plaster inground) every week.

Just an F.Y.I.

Thanks. This is just one of those areas with multiple factors. Lowering TA does help, but doesn't always help that much.

Not having any bubbles at all doesn't make that much sense since there should at least be hydrogen gas bubbles since I would expect the water to get close to fully saturated and for the hydrogen bubbles to outgas -- at least by the end of the day with the SWG still running. You might take a look at night with an interior pool light turned on (and, obviously, turning on the pump and SWG). Many times people don't see bubbles during the day, but can readily see them at night.

I'll have to keep thought in mind as I can't see squat right now thanks to Hurricane Ike and no power. If I ever get back in (running out of season now) I'll post back.
