Hanna Checkers

.05 is fine. just run a little gfo to keep it there with feedings. you need some po4. I always aim to be under .1
Pife is right 5 nitrate and .03 is considered ideal for sps tanks. I run a mixed tank so .05-.08 is good.
 
I have 2 bags with carbon and gfo in between baffles in my sump. Also use chaeto. I am going for mixed reef as well. Wondering how to slightly elevate NO3.

Feedings and/or Potassium Nitrate dosing. I prefer feeding.
