    Nitrate checking liquid 2/28/2015

    Reviewer: Jerry Hames

    I use API Nitrate test solution. Because I have trouble telling the difference in the 40 & 80ppm Nitrate, I bought the calibration solution and tested my API Nitrate test kit. I found that the 1ppm showed 5ppm with API, the 10ppm showed 80ppm on the API test kit, and the 100ppm solution showed 160 on the API Nitrate test. I've been concerned and worried about my aquarium Nitrate levels for some time now. I raise goldfish and must feed my babies 3 or 4 times a day. My filters keep up, but the Nitrate was high. I'm glad to know it's not as high as I thought.
