Finding nitrates

Nitrates have been steady, no noticeable fluctuations, I did add a healthy size cuc to the rock bin to see if that helped with detritus.
And yes just trying to find the difference from other tanks as rock payment is only difference.
Currently using a red sea test kit. But I'll get a salifert to check also. I have had the red sea for 6/8 months and know they break down once opened
