to keep it simple, animals and plants help each other. land, Fw or salt that is just the way it is. In aquariums we place livestock at much higher concentrations then in the wild. Therefore, we should also have plant life at much higher concentrations as well. My Fw have sand water fish, plants, and a light. By just feeding the fish, replacing evaporative water, using tap, every 4-6 months removing a very light algae, and nothing else they have ran for up 6 continuous years from the original two fish that cycled the tank. Salt require more effort but so does most FW also. In my experience salt requires some circulation and helper filtration. But the basic idea remains the same.
to get more detailed as robert fenner says:
Benefits:
1) Bio-filtering: Macro-algae can aid considerably in establishing and stabilizing new or "out-of-whack" systems. They bring in and help to institute micro-organism communities, absorb nutrients introduced by food, decor and tap water. For systems with invertebrates, particularly anemones and live corals, live plant material can be especially helpful in improving water quality. In sufficient growing strength, macro-algae will remove nitrates, assist in buffering pH, uptake carbon dioxide producing oxygen, and assist in balancing trace elements (e.g. magnesium, phosphate, iron)
To some extent they are useful as bio-indicators; real-time monitors of the viability of the system. If your macro-algae will not live and grow, or start dying back, it is a warning sign that something is out of kilter chemically, physically and/or biologically.
2) Algae Control: Having a batch of algae intentionally growing in the system will go a long way in limiting the growth of unwanted forms (slime, string algae, fungus and bacteria) by competing for light, space and nutrients. For you reef-keepers, be aware that over-zealous algal growth may affect coral health through nutrient competition, smothering and possibly metabolite poisoning.
3) Food: Many, if not most of the marine fishes and invertebrates we keep augment their diets with large algae. What better deal than to have some continuously available for casual munching? Similar to our own nutrition, many trace nutrients make their way through this cycle.
4) Habitat/Ornament: macro-algae serve to break up the physical environment, affording hiding space from tank bullies and aquarists, and piece of mind to the inhabitants. Beyond this, they are aesthetically attractive; sheer beauty in terms of color, shape, size and motion.
