Hi folks
Two weeks ago it got cold and my SWG stopped working well. I was going abroad for a week, so I dumped a few trichlor pucks in the inline chlorinator... Came back home to find FC levels tru the roof 20+.. removed all residual pucks from chlorinator and turned off SWG. Thing is, it's been that high for nearly two weeks now and levels don't seem to go down...I'm assuming because it's been two weeks of really cloudy weather with limited UV (I also put a leaf net over the pool during this time and wonder whether that is limiting UV materially too though I wouldn't think so).
No one is swimming but I'm afraid to damage equipment with FC that high for that long...

Is there anything else I can do to lower FC (short of dumping water and refilling of course)? And how dangerous is this to my equipment and liner??

Thx all!

Hey MC !! Up to and including Slam level is safe. (40% of your CYA). So if the CyA is still 60, that’s 24 FC. Let it ride and you’re dang near perfect to close whenever it’s convenient.
