I have a recently set up planted tank and have a question about how the cycle works in a planted tank. I am fully aware of how the nitrogen cycle works, but need help on my first planted tank. I set the tank up with media I had in a filter from my cycled tank that has been in there for about a month. After a couple of days I noticed .25 ppm of ammonia. I left the ammonia in the tank since it was not at a dangerous level, and I was going to do a water change if it got up to .5 ppm. The next day there was 0 ammonia, 0 nitrite, and 5-10 nitrates (my tap water has 10 nitrates). My question is: is my tank not cycled since the plants absorb the ammonia and not the bacteria.
