Ok so I finally went high tech lol and picked up a profilux and would like to no what levels should I be at for.
Redox
Ph
Conductivity
There are a lot of variables in any recommendation for parameters, most set-ups develop their own "sweet spots" over time.
However, in my reef (now 3 years old) my Profilux says:
Ph ...... from 8.32 to 8.45 (day/night variation)
Conductivity..... 52 Ms (equal to 35.0 salinity and somewhat temperature dependant due to density change with temperature.
Redox...the $64 question ! Many reefers dont use redox for a parameter, but I do. I dont use any absolute number but use it a a guide as to whether the water is improving or not. Typically I have Redox of 425 overnite, falling to 400 ish during the day.
