Hi, we are new to a saltwater tank and have a few questions. We have a 55 gal. tank with crush coral bottom. I have this brownish stuff growing on most everything from the fake coral rock I have to the back of the tank. I am wondering if this is normal or should I be concerned about this. All of our readings are good except the Nitrites, are sky high. What can I do to help get these to come down? I have read several forums and I noticed I should throw a dead shrimp in there to help my cycle. We have had the tank up and running for 6 weeks. Everything was going good until my husband did a water change, and cleaned the filters in one day. I think he threw us back to step one by doing this all in one day. So I guess what I am wondering is, is the brown stuff good and if not how can i get rid of it. Thank You
