I am finishing my tank cycle. Ammonica is at 0 and I am testing my Nitrites with a Salifert test. When I perform the test and read the results looking down from the top, as instructed, I see no color. The test does say that AFTER the tank has cycled you need a higher sensitivity test and to view the results from the side. If I do this now I do see a slight hint of pink color. Would you consider the tank cycled at this point?
