saltwater is not that much harder than freshwater. once you get things down its like second nature. Some may even say its easier than freshwater because thing take care of themselves. although you will still need to so some work. the hardest part of saltwater is first starting, and waiting for the tank to cycle. the easiest way to cycle a tank is with live rock in it. and during the cycle you will have to constantly check the water parameters. but after that you should only have to do it once a week.
