Aquatic plants are frequently used in aquaculture to purify freshwater ecosystems. Plants play an integral nitrogen purifier in the overall health of aquariums, ornamental ponds, wetlands or natural aquatic ecosystems.

 Nitrogen Reduction
Almost all aquatic plants remove nitrogen purifier associated with waste and decay--from the water. This can prevent the overgrowth of nitrate-loving algae blooms.

 Oxygen Supply
Plants produce oxygen as a natural by-product of photosynthesis. A steady oxygen supply is crucial for the survival of aquatic fish and invertebrates.

 Ammonia Reduction
Many nitrogen purifier plants help to absorb dissolved ammonia from water.

 Heavy Metals
Some wetland-dwelling plants, including cattails and bulrushes, may be capable of removing heavy metals from water. To prevent recontamination, mature plants must be removed and placed in toxic-waste landfills.

 Potential
In the future, aquatic plants may be used more extensively in municipal water nitrogen purifier. They provide one of the only reliable methods for removing nitrogen-based pollutants from waste water.
