Waste great advice, we do run the pump for a minimum of 4 (typically I just spin it up to 12 hours) hours after anyone has been swimming. I added a spring wind timer that overrides the compool setting and we run it every time. I also run the pump in low speed for 15 hours a day, maybe overkill but I feel better and with the two speed pump in low speed it isn’t bad electricity wise.

Sean yes our pool is heated, to much I think, but my wife won’t go in it otherwise, so it is about 88F.

Yes we top off our pool with water from the bay of Green Bay an inlet off Lake Michigan. Our well water is about 1800 ppm TDS, very hard and has a lot of metals in it. The bay is about 50 ppm TDS and is quite soft, but being a large body of water has its share of algae and other small living things. We do filter it though four 5 micron filters before it hits the pool and shock the heck out of it when I add any significant amount. I have been refilling the pool every other year and this is a refill year. I would get the water cleaned up and balanced before I ever installed or turned on a salt system.

And yes this helps a lot, my understanding of how this all work is much better.
