So I'm almost 2 weeks into my cycle, I've got a 28 gallon tank with 2 filters (tetra whisper ex45 and fluval u2) and 10 golden white cloud mountain minnows.
I've been making water changes every 2 or 3 days, about 5 gallons every time. I've been using tetra strips, which I know are inferior and might be the cause of my question, but I'll buy the api master kit when I'm closer to running out of the strips.
I don't have a heater in there right now, so the water is about room temperature.
Here are my test results from this morning:
A few days ago, my nitrites were about 3.0 and my nitrates were about 20, and my test results were the same yesterday as they were today. Should i be concerned?
I know my tap water is very soft, but I also seem to have zero alkalinity? Any cause for concern there too?
