@Rancho Cost-a-Lotta - Thank you! I did a bunch of reading on SWG & stone. I’m none the wiser as a result LOL.@Triumph65 When searching for swgs, remember not all 60,000 gallon units are the same. Compare chlorine production in pounds per day. Pureline (Inyo Pool) has a 60k unit that's rated at 3.18 lb per day.
Maybe I should take some pics of my pool and post it in SWG forum to ask about stone. You think that’s the best forum category?
My pool is a little different in that I have a bunch of the flagstone below the waterline.
Thanks for your help! I appreciate it.
