Seachem Pond Matrix

Seachem Pond Matrix is used for high-capacity biofiltration in ponds to control ammonia, nitrite, and nitrate while supporting aerobic and anaerobic bacteria species.

  • High capacity biofiltration
  • Controls ammonia, nitrite, and nitrate
  • Highly porous - enormous surface area (160,000 cm2/L)
  • Supports aerobic and anaerobic bacteria species

Pond Matrix™ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste in ponds. Plastic bio-materials provide only external surface area, whereas Pond Matrix™ provides internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Pond Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Pond Matrix™ is completely inert and will not breakdown. It need not be replaced. It is also more suitable for use as a clean soil replacement for growing pond plants. Use 1–2 Liters of Pond Matrix™ for each 100 US gallons. Since the majority of the bacteria are internal, Pond Matrix™ may be rinsed when needed without damaging the filter. Pond Matrix™ is compatible with all types of wet or wet-dry filters.

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 overlayered 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.

Convenience is king (or queen) for a busy person
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
I use these plates a lot. Nice looking, nice weight and finish. Good for a quick bite or reheating something in the microwave. Thick enough and heavy enough not to leak. I use 3 different sizes, price is right

Mini paper plates
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
These smaller paper plates are perfect for a quick lunch when you don't need a big plate but just something quick for a sandwich or a dessert. I love these plates because they are so durable. They're sturdy and the value is amazing. I've checked everywhere on pricing and you can't really beat Amazon's prices for these. Additionally, they always arrive on time and they are always packed well. I've been using these for years. I love them. They make my life much easier. (:

Good plates but someone can't count
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
Good plates, exactly what I needed. Sold as 2 packs of 300 but only 1 pack of 300 arrived. Since this is an Amazon deal, they don't give you a way to talk to a seller, only let you make "suggestions" for the future. Only recourse given at that point to to return for a refund. It would appear sending half the order is a common issue with this particular offer.
