newtofish1994: I'm going to return this thread to its purpose - getting your tank going. The web site you gave as a source for your fish-iin cycling is way off base, IMHO. First of all, it is a freshwater site, not marine, and the systems are different, and rely on different kinds of filtration. Secondly, they guy says that only new aquariasts insist on fishless cycling, but this is not so. I have been keeping marine systems for almost 40 years with great success, and I know what I am doing (I have a Ph.D. in animal physiology). Using damsels to cycle a tank creates two problems. 1) as I have said, it is unnecessarily cruel and painful to the fish, and 2) damsels are horrible fish (if any fish "deserves" to have its gills burned, it would be damsels) that become very territorial and will kill later additions to the tank. They will even attack your hand, and draw blood. They are also very clever, and virtually impossible to remove from the tank since they hide well, and you eventually have to remove all of the lr to get to the fish. Don't do it. If you add enough live rock that is in good shape (bought from a nearby lfs and transported wet to your tank) it will have sufficient bacteria present to produce a soft cycle - that is, a single fish will not produce an ammonium spike, and you can add additional fish every couple of weeks without problem. Since you are talking about a 10 gallon tank, you won;t be adding more than one additional fish at most. Be aware that the only tank more difficult to maintain is a 5 gallon system since these very small tanks are very unstable, and the key to success in marine fishkeeping is water stability. Most of us consider a 10 gallon tank to be the hardware equivalent of a moorish idol - "expert only". Your best bet is to be a little patient since in my nearly 40 years of fishkeeping I don't think I have ever seen anything good happen to a tank that was rushed.
