For about the past week or so my Nitrates have been going up, little by little. The highest they achieved was about 7 or so. Today I tested again and they are at 0. I'm going to test again tomorrow, but I was wondering if Nitrates at 0 are a bad thing. My readings are:
Ammonia 0
Nitrates 0
Nitrites 0
pH 7.8
