The only plants that I keep in my tank are macroalgae. A lot of people in the hobby do this for nutrient absorbtion and others do because they like the look of the macroalgae in the display. I personally keep it in my sump refugium.
Mostly for greens and other colors, we keep corals. The demand is a little higher than planted freshwater tanks, but not much. Testing Alkalinity and Calcium become even more crucial, as corals use calcium in the water column to calcify their skeletal structure.
Do a google search for saltwater tanks and let us know what look you are going for.
