I have been cycling a 75 gallon tank and my ammonia went up and nitrites went up and now there are no nitrites but, I still have ammonia. The nitrates are up also. So it seems like it cycled and is starting to cycle again. Is this right? The reason I ask is because I thought ammonia dropped before nitrites did. It has been over 2 years since I cycled one so I am running on fuzzy memories. If anyone can tell me if it is starting over or if it is going in the correct direction just let me know. The water is at: Nitrate 10-20 Ammonia 0.50-1.0 Nitrite 0 Salinity is at 1.23-1.24 Thanks Chris.
