This family of sea grass is normally found in sub-tropic waters.
Most of these sea grasses are found in tropical waters.

The process of introducing carbon into the aquarium water through carbon dioxide fertilization does little to help in the growth of marine macro algae, but it would benefit a sea grass dominated system.
Seagrass beds are highly diverse and productive ..
In both systems the physical aspects of the tank design - particularly light and substrate requirements - are the most important. The approach that best fits an individual aquarist depends solely on the goals for the display in question. In lagoon style tanks the emphasis is on corals, and the seagrass is more or less a "highlighting" species. Since the biomass of plants is small, their nutrient demands tend to be low and are easily met by organic sources of nutrients within the tank (which we will cover shortly). There are already examples of systems such as this among Reef Central members (, , ). Seagrass dominated aquaria attempt to grow large stands of seagrasses and macroalgae and tend to have high nutrient demands that cannot always be met by organic sources alone. For some of these systems, inorganic sources of nutrients are dosed similar to what is already done in freshwater aquaria to maximize the plants' growth. Nutrient dosing in marine aquariums is admittedly atypical, and is covered briefly below as a preliminary guide for aquarists who are interested in marine planted tanks.
