Hey everybody. I haven't been able to get my nitrates under 40-80 ppm (I have a really hard time telling the colors apart. They look so similar...) so I decided to test my tap water. It tested the same 40-80 ppm. What am I supposed to do about this? Am I just testing wrong? I follow the instructions exactly and bang the second bottle again my palm while I shake it for a long time. If the nitrates in my tap water really are that high, then what?
