Hi everyone, I'm struggling with a fishless cycle and getting some weird results. Hope some of the experts can shed some light on the issues. Started with a brand new tank, substrate, purigem insert and bio material (using the Fluval Spec V tank) Added treated water with Seachem. Waited 24 hours before introducing One and Only bacteria + 5ppm pure ammonia. The numbers I'll give are Ammonia / Nitrites / Nitrates Day 1: 3ppm / 0ppm / 0ppm Day 2: 3ppm / 0ppm / 0ppm Day 4: 2ppm / 0ppm / 0ppm Day 5: 2ppm / 0ppm / 0ppm Day 6: 4ppm / 0ppm / 0ppm (added more ammonia) Day 7: 4ppm / 0ppm / 0ppm Day 8: 3ppm / 0ppm / 0ppm Day 9: 3ppm / 0ppm / 5ppm Day 10: 3ppm / 0ppm / 5ppm So it appears that NITRATES are showing up but ammonia is still high. And I never saw an increase in nitrite values. What on earth is going on? Should I do a water change? Can't seem to bring ammonia levels down.
