When I look at the recommended levels for Vinyl pool (Pool School - Recommended Levels). Below is what I get but when I go to the poolmath calculator it's slightly different. So Can someone tell me the ideal numbers?
For FC it seems straight forward. If CYA is 30 ideal is 4ppm (Pool School - Chlorine / CYA Chart). But for the others there doesn't seem to be an ideal? In other words should ph be 7.2 ideally or 7.5, etc. Thank you!
