So I have a 3 almost 4 week old 29g tank with 3 fish. I just did a water test and it came as 0ppm Ammonia, 0ppm Nitrite, 40ppm nitrate. A few days ago it was .50ppm Ammonia and 0ppm Nitrite. Is my tank finally cycled? Yesterday I put seachem prime to protect my fish from the ammonia. Is that why it says 0 for the test? What does seachem really do? PS- I think the Nitrate came from my tap water because I tested it and it did came back as 40 Nitrate.
