Why isn't my hammer bright green like in the lfs?

Are your rocks old? Like did they come from an older tank? Your nitrite problem could be coming off your rocks. I have had this problem in the past.

These rocks were fresh tonga rocks. Had about 2-3 months of cycling before adding any livestock. The levels were all good at that point.
