I started a new 15G planted tank about two months ago. I used a filter pad from my 29G Whisper filter in the Whisper filter on this one and the measurements were fine for a while (Ammonia 0, Nitirites 0, and Nitrates steadily climbing from 5 to more than 20 two weeks ago).
Once Nitrates hit 10-15 a month ago, I gradually added fish from the 29G where I now have 6 neons, 2 corries, 3 otto's, and 2 head and taillight tetra's in there. Plants are thriving and fish seem happy.
However, during the past week I started seeing more and more brown particles (waste?) appear in the water and this week's measurements showed that the Nitrates dropped to something undetectable.
It sure looks like a cycle problem and I added a couple of capfulls of Cycle, but I do not know what else to do.
Any input is appreciated.
