Re: Formula for SWG / Pump Runtime?
I was just going to post a thread asking if my math was right, as I'm trying to determine the same thing. My Pentair IC40 is standalone, and my choices are only 20%, 40%, 60%, 80%, or short-term 100% for 24 hours.
I converted output to ounces/hour, then gallons of pool *8#/gal *16 to get to ounces, figured how many 'millions parts' of water I had, then factored *4 to get to my 'needed' 4ppm daily increase to offset sun and bather load. Divided by my percentage production per hour to get a starting point.
Like others, I had been told about 8 hours a day at 40% should work fine, until I got a mild algae bloom and had a 2 week slam.

I'm coming off a slam, so I've been losing 3-3.5/day due to sun, when I had the SWG unplugged. Much harder when SWG is running and hitting a moving target.

Excellent work.

Thank you. A ballpark is what I was looking for. It would at least shorten the trial and error. Ones i got the formula working, it instantly helped me realize I why it "was not keeping up". It just was not running enough. Mmn The
Probably need to document a process to calculate the daily FC PPM loss.
