Hello, I am new to the hobby but I have done so much research on subject that I thought I knew what I was doing, apparently not. I bought a new 20 gallon tank and it has been running for about a month now and there's no signs of the cycle starting. I have a quartz sand substrate, a few Seiryu rocks, some spider driftwood, 3 java ferns, java moss and spangles on top. I upgraded the filter to the Fluvul 50 for extra media space and increased filtration. So far I have used 2 bottle of tetra safe start with no luck. All of my parameters have been constant too. Temperature is 78 degrees, pH holds steady at 8.0, and I have dosed with pure ammonia up to 2ppm. In the month it has been running, there hasn't been any sign of nitrites or nitrates. I am at a complete loss as to why it will not cycle. All water was treated prior to adding it to the tank. Does anyone have any ideas what I'm doing wrong?
