Hi all, been a while since I've been around. I had a question about cycling a new tank, and you folks are pretty much the most knowledgeable ones I know.
I've had a sparsely planted tank set up and cycling with a couple tetras for a little over a month. My water quality tests are coming back... weird.
For the first few weeks I was showing ammonia, and nothing else as expected, but here recently, I'm suddenly showing ammonia and nitrates, but no nitrites. All of my fish-related knowledge tells me that this shouldn't really be possible. I haven't been doing any water changes during this time, just testing the water to make sure it wasn't getting too unbearable during the cycle.
Has anyone ever experienced this? Cause this will be my 6th tank, and I've certainly never seen it. I do have a bit of an algae problem in the tank, almost as soon as we were up and running, brown algae got EVERYWHERE. Could this be part of the problem? And how on earth do I get back on track?
