Hi I am currently in a fishless cycle in a planted tank and have been for approximately 3 weeks adding 2-4ppm ammonia this is now being reduced to 0ppm within 12/16 hours. The Nitrites have stayed steady at .25ppm all the time and not increased or decreased. The Nitrates are around 5-10 ppm closer to 5. I have also added stability on a regular basis. What is happening ?? Can I do a partial water change to dilute the Nitrites and then safely add fish and stability at the recommended dose and time period along with Prime. Your advice is very much appreciated.
