I just picked up a Circupool Rj30 classic for my 10,000 gal pool that should be here in a few days. I want to get my pool chemistry ready before it arrives so I'm ready to install. Anyway, I noticed in the pool math calculator that traditional pool ch range it 200-400 while trouble free is 350-450. Do you guys suggest shooting for the trouble free numbers? How come they are so much higher? How early can I add the salt before installing the SWG? I have a Taylor 2006 test kit, can I buy just the regents to test for salt?
