We have had fish in our new 110 gallon tank for a week. 7 fish total at almost 2 inches each. We made sure our water parameters were ok before the fish and they are the same as of last night even with the fish. We use the API liquid test kits. My concern is reading the colors on the card. The nitrite is definitely always 0. The ammonia is never the bright yellow color that is supposed to be 0. It looks to us more between 0 and 0.25 and with the fish in, even more of the 0.25 side. The nitrate is 10. Our pH is currently 7.4 and our temp is 78.6. How accurate are the test kits and should I be worried that our results seem to be between colors? I know how dangerous any nitrite or ammonia in the tank can be and I definitely do not want to kill any fish.
