Im well versed with the theory behind a fishless cycle. My attempt at it did not go exactly via the book though! hehehe. Always hold the test tube against the color-chart, not to let any light inbetween the testtube and the chart. LOL
I just thought that a water change "fixed" the bad ammonia levels when they were Off-the-charts high, that the same must happen now for nitrites too...
Well, waiting patiently then!
