Seachem® Water Garden Oasis Pond Matrix™
Seachem® Water Garden Oasis Pond Matrix™


* Promotes a healthy environment for both fish and aquatic plants
* Controls ammonia, nitrite, and nitrate in decorative ponds
* Supports aerobic and anaerobic bacteria species

Keep your pond in tip-top shape with a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Unlike plastic bio-materials that only offer external surface area, the Water Garden Oasis Pond Matrix provides internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows the biomedia to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.

Water Garden Oasis Pond Matrix is completely inert and will not breakdown. Suitable for use as a clean soil replacement for growing pond plants. Use two Liters of Pond Matrix for each 200 US gallons.

Directions: For filtration use 2 Liters of Pond Matrix for each 200 gallons of water. Use in any pond filter. Pond Matrix is sufficiently large that a filter bag should not be necessary. Follow the manufacturer's recommendations for your filter. Pond Matrix should never need replacing. Pond Matrix makes an excellent support for root development of aquatic plants and may be used directly on the bottom of the pond or in pots. This avoids the use of soil in the pond. It may be used alone, mixed, or layered with river rock. For pond bottom use, it should be presoaked for several days and allowed to become water-logged and sink (although a high current will disrupt it). Pond Matrix is inorganic and will not decompose or pollute the water.
