I've just setup my first saltwater tank. I've used RODI water and mixed the salt. Do I need anything to start cycling the tank? After it's cycled I plan on stocking it with True Percula, a Watchman Goby, and an Orchid Dotty back. Aside from the True Percula being the first fish in the tank, what order should I stock them in? It will also be a reef tank, much later.
