I got done with a slam a few weeks ago. I have my cya at 50/60. I've been doing trial and error with the swg to dial it in at the lower cya. So my question is. Tonight I tested my Fc and it's at 4.5. Which is 0.5 less than the 5 minimum recommended in pool math (normal without swg). Should I slam or should I be good since I am still over the 3 recommended with a swg (even though my cya is much lower than swg recommendation). I guess this question more so asks, is pool math accurate, if you are not within the recommended ranges? I am going to bring up my cya to 70ppm. Thank you
