Hello friends! I'm really happy to be back for another season!

Pool was opened up last week and I've been working on getting all of my levels dialed in. One general question I had is, and I know there isn't a de facto rule because there are so many factors, but... Assuming that all of my levels are "perfect" and looking at my pool specs, what percentage of output should I set my SWG at just to "maintain"? I run my pump at 3200rpm beginning at 7AM for 3 hours, then at 2400rpm for 10 hours, and then at 1500rpm for 9 hours overnight. My SWG can be at 2%, 4%, 6%, 8%, 10%, 20%, 40%, 60%, 80%, or 100% of output. I know that fluctuations will happen, but which output percentage would be a good start to maintain chlorine level, knowing that adjustments will still need to be made from time to time?

Thanks!
 
The IC20 can output 0.7 pounds of chlorine gas in 24 hours. In a 13000 gallon pool that is equivalent to 6 ppm FC.

The average TFPC pool loses 2-4 ppm FC during the summer. So to replace that you'll want 30-70% of your SWG output. Assuming you are running it 24 hours (you're missing two hours in your schedule) I'd probably start at 40% and adjust it up or down from there based on what direction your FC is moving day to day.

I appreciate the reply and help! Also, please don't tell my mother (former teacher) that I don't know how many hours are in the day apparently, haha. Yes, the schedule runs the pump 24 hours, I'm just intellectually challenged it would appear.
