Attempting to fishless cycle my 90 gallon...I poured ammonia in and am thinking I have too much...I am using a good testing kit but notice that the card kind of stops at 4ppm and next color is 8ppm....mine is in between....thinking I could even be as high as 6 or 7....is this too high to get nitrites to form. Been like 10 days and little change in ammonia level.
