can someone give a little detail on what it is and what the value should be with our apex probes?

Also why do we want to know the value and what can we do/automate with that information?

I describe everything you'd want to know about it here:

Other than stopping the addition of ozone if you are adding too much, I wouldn't automate anything with it.
