I started my 29 gal
saltwater tank about week ago. I used crushed coral sand, dead rock, and some artificial plants to kind of get started. I let the tank run on its own for a few days, and i was told i could add a couple fish to help kick off the cycling of a new tank. so, i added one clown fish and a hermit crab. they seem to be doing fine, but now the tank is starting to show trace amount of ammonia and nitrites, which i understand it should as part of the new cycling process. so at this point im just a little concerned at what should be happening next. any advice would be awesome.
