Well, The number one thing you need to do is read as much as possible and use good advice. Patience is very important. I dont think saltwater can be considered easy compared to freshwater. There are so many variables. Live rock, fish, inverts, skimmers, r/o units, lighting, u/v,wet/drys and dreaded diseases. Ick in saltwater is alot harder to get rid of then freshwater depending on whats in your tank. Not to mention if you lose any live stock its not just a couple of dollars. This hobby is very expensive compared to fresh. Once your tank is stable it is pretty easy to keep as long as you do what you are suppose to like not overcrowd, not overfeed, keep your water clean, RESIST impulse buying , quarentine all new fish and the list goes on. Im not trying to discourage you,I love this hobby, but read and use what you have read or you will be sorry.
