Api test kit showing 0 ppm nitrates

Brendoboi

I have had a 10 gallon cycled tank for about 8 weeks. I tested my aquarium for nitrates and it showed 0 ppm for Ammonia, nitrites, and nitrates. I have 4 fish, 2 mollies and 2 platys, I also have a big java fern. Why would my aquarium show 0 nitrates? Last week my aquarium showed 5 ppm nitrates and .25 ppm ammonia.

Make sure you're really shaking bottle #2. That bottle tends to separate out a little bit, and give innaccurate tests, if you're not careful

Good! The .25 PPM ammonia reading you got is probably 0 - the API ammonia tests give .25 PPM false positives a lot. Nothing to worry about, unless it creeps higher!
