Hi everyone, great website and forum. I just started my 55 gallon tank and read a book on how to cycle. As a result I started with 5 zebra danios. I now know I should have perhaps gone the fishless cycle method, but here I am. The issue seems to be that my ammonia won't build up. It has stayed at .25ppm for about a week now. No trace signs of nitrite or nitrate. The fish seem very happy. Is this simply a matter of patentiently waitng for the biological filter to kick in and daily water monitoring or should I be doing something else?
