Not initially no, I threw some in later at the advice of the LFS but that seemed to make things way worse so I didn't do it again. I do have a badge but it says everything is fine when the test kit and behavior clearly shows otherwise.Did you cycle the DT with any bottled bacteria? If so how long ago? I just use one of the badges to let me know if ammonia is present, they aren't accurate as to how much ammonia but it seems to be accurate that there is or isn't any there.
