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.

Quality Wipers
Size: Combo Pack (23" & 19"), Style: Top Lock Narrow
These Bosch Aerotwin wipers are a perfect fit for my 2020 Audi Q5 and work exactly as expected. Installation was quick and straightforward, and they snapped right into place with no issues. They wipe smoothly and quietly, leaving the windshield crystal clear even during heavy rain. Performance feels very close to OEM quality—no streaking, no skipping, just consistent and reliable cleaning. They also hold up well at highway speeds without lifting or making noise. Overall, a great upgrade or replacement for the Q5. Highly recommend if you want dependable, factory-style performance without paying dealership prices.
