Description

Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix provides as much surface (>~700 m2) as 170 liters of plastic balls. Plastic bio-materials provide only external surface area, whereas Matrix provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.

Matrix is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix may be rinsed when needed without damaging the filter. Matrix is compatible with all types of wet or wet-dry filters.

Features

  • High porosity biomedia for efficient biofiltration
  • Both external and internal macroporous surface area
  • Completely inert and will not breakdown

Usage

Use 250 mL of Matrix for each 200 L (50 US gallons) of water. Matrix may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix is sufficiently large that no filter bag should be required for most applications. Matrix™ works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications. Use with Stability® to more rapidly establish the bio-filter.

This dosage may differ from your packaging. Based on updated studies, Matrix was found to treat even more water than previously asserted.

For a Dennerle 55 l aquarium, 68 ml of Seachem Matrix is needed. However, many aquascapers use 1,000 ml per 100 l of aquarium water.

So I shouldn't use this product if I have a planted aquarium and want nitrate and other nutrients for my plants, because it especially breaks down nitrate! Is that right?

Seachem Matrix can break down nitrate in small amounts through anaerobic zones. These zones are much less present than with sintered glass products. If the medium is rinsed regularly in aquarium water, there should be no adverse effects.

Hi everyone, how much do I need if I want to fill an Oase BioMaster Thermo - 850 with this material? So that I can fill 2 baskets with it. Thanks, and keep it up. Best, matze

The filter baskets of the Oase BioMaster Thermo 850 can each be filled with filter media up to a volume of 800 ml. If you want to fill two baskets with it, a total of 1,600 ml of filter material is needed. The amount of Seachem Matrix that can be used depends on the size of the aquarium. The manufacturer recommends using 250 ml of Matrix per 200 liters of water. To make sure the porous filter medium doesn't get flushed out of the filter baskets, a mesh bag such as the Seachem Zip Bag is recommended. https://www.aquasabi.de/Seachem-Zip-Bag

Dauerbrenner

Verwende Seachem Matrix in all meinen Aquarien und habe mir kürzlich auch den 20l Behälter zugelegt. Verwende mehr als die angegebene Menge /Liter und fahre echt gut damit. Leicht zu reinigen, große Siedlungsfläche für Bakterien.

Use it in the Juwel Lido 200. Filters the water great. Since I started using Seachem products I've had crystal-clear water.
