Bio-spira.. Yeah thats the stuff...... I would say your if you never saw a big ammonia spike that there is no way your tank is cycled with the info you gave. I am not a firm believer in fishless cycles either. Not saying it won't work... thats just my opinion. In reality there is not much of an excuse imo to lose any fish durning a cycle anyway. It is called a water change. I get a little confused myself when so many people talk about losing fish while cycleing. My 220 I lost about 12 of the feeder gold fish (out of 50) that were about to die before I put them in. The 12 Convicts that the store gave me are still alive and kicking.
