Since your T/A is 200ppm in a F/G pool, I think you are close to done on that--anything under 180ppm you should be OK.

A CYA of 40 or 50 is great--you'll use less chlorine but it won't break down in sunlight.

TDS is nonsense 99% of the time (every SWG owner has TDS that's "too high").

And, of course, phosphates is the latest scare tactic. Only worry about phosphates when our cleanup methods don't work.

I think you are doing great!
