I have had my tank set up for 2 weeks now trying a fishless cycle. I added amonia at the start to get it up to 5ppm, and still after 2 weeks, no nitrites and the ammonia is the same. I was at the store today and picked up some biozyme that i saw there, but just thought I'd check on the forum here to see if it is good a thing or not to use that. Will that speed up the cycling, or am I better off just letting it do it on its own?
