Directions

Use 500 mL of Matrix™ for each 200 L (50 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.

Surface Area of Matrix, Eheim Substrat Pro, and JBL MicroMec

Two competitors, Eheim (Substrat Pro) and JBL (MicroMec) have advertised their own biological filter media (in both cases, sintered glass) and are claiming larger specific surface areas than our claim for Matrix.

For biological filter media, specific surface area (measured as surface area per gram of material, or surface area per some specified volume of material) is very important. These products provide surface sites for bacteria to attach and do their work. The greater the surface area per gram of medium, the greater the number of bacteria that can attach. Thus a high specific surface area is desirable.

There is a second consideration, and that is the size of the pores in the medium. Generally, with very large pore diameters, we have smaller specific surface area, so that is not good. This generally rules out pores above 10 microns in diameter. But we can go too far in the other direction. If we have a very large number of very, very small pores, then our specific surface area number will be phenomenal, but the medium will not work very well as a biological medium. This is due to physical limitations, specifically too small a volume to support bacterial growth, and the decreasing efficiency of fluid transport (necessary to carry nutrients to the bacteria and waste away from the bacteria) with very small pore sizes. (Small pores still play important roles in physical and chemical processes, such as adsorption.)

BET surface area measurements indicate that Matrix™ contains nearly 10 times the specific surface area of Substrat Pro, and more than 20 times the specific surface area of MicroMec. Practically all the specific surface area of both Substrat Pro and MicroMec are in the range of pore diameters to be biologically useful, while some of the surface area of Matrix is in pores that are reserved for physical and chemical processes, not biological processes. Estimates from two different pore geometries indicate that Matrix contains between 4 to 4.5 times the biologically active surface area of Substrat Pro, and between 8 to 9 times the biologically active surface area of MicroMec.

Each filter has three roles in a planted aquarium. In order of importance:

NITRIFICATION
It is the most important! Toxic and algae-causing ammonia in the aquarium must be decomposed. As fast as possible. Billions of bacteria growing in the filter convert ammonia into nitrite and then nitrate.

WATER CIRCULATION
Nutrients (plant food and CO2) must reach the plants. Solid decomposition products should be kept afloat. Good performance is essential.

WATER TREATMENT
Solid decomposition products must be physically removed from the aquarium and decomposed in a filter or removed during cleaning.

For a filter to fully perform all three roles, it must meet several criteria. Ideally suitable to have a bucket of the right size to store the right amount of filter media. The filter material contained in it must be of adequate quality and variety. The pump in the filter must have sufficient capacity. The filter should be easy to clean so that the cumbersome process does not deter the aquarist from regular maintenance. Plus, the filter needs to be reliable; no one wants to flood a living room or office due to a cracked tap or joint.
