Hello, I get a bit frustrated with my API master test kit sometimes. I find the colors hard to read. Usually nirtrites are the easiest, but I'm having a hard time with this. What would you say this is? 2ppm? While we're at it, how about my nitrates? I find it impossible to tell the difference between 40 and 80. I know for tank maintenaince it shouldn't be that big of a deal, since you would want to do a water change any time it's over 20, but for fishless cycling I would really like to see if the nitrates are going up... If the nitrites are in fact 2, do you think I should do a water change? Yesterday was the first day I saw nitrites. Yesterday it was clearly .25. And finally, since we're on the subject, anyone know of a better test kit that's easier to read? I haven't been able to find one. Thanks so much for your help!
