I tested the water yesterday, and tonight the nitrate test seems to be showing up a slightly lighter shade. Nitrites are off the chart and i need to add more ammonia. Could this just be that i didn't shake the second nitrate test bottle enough yesterday? I'm certain i did it right tonight even banging the second bottle a few times on a hard surface before giving it a hard shake for at least 30 seconds.
