Product Information

Seachem Matrix removes nitrate, ammonia and nitrite, simultaneously and is compatible with all types of wet and dry filters. Matrix bio-filtration uses tiny balls about 10mm in diameter to act as a filter medium. The porous inorganic solids have a great surface area - as much as 170 litres of plastic balls. Whereas plastic filter balls only offer the external surface area, Matrix have both the external and internal macroporous surface area. The macropores in the filter medium are ideally sized for the support of nitrifying and denitrifying bacteria.

Matrix is inert and won't break down, so it doesn't need to be replaced - it can just be rinsed as required. Remember to rinse in old aquarium water to preserve the bacteria. Matrix may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix is quite large, so a filter bag shouldn't be required for most applications

Key Features:

  • Removes nitrate, ammonia and nitrite
  • Compatible with all types of wet and dry filters
  • Wont break down, so doesn't need replacing

Dosage:

Use 500 ml of Matrix for each 200 L of water.

    Best biomedia for aquariums, I use it in all my tanks and I'm sure it keeps water quality tip top, along with the regular water changes of course.

    The irregular shapes mean that they can fill leftover spaces that many other biological media can't, enabling majority of space to be utilised.

    Run 12 litres of this in one system and in all my others to.Only one small problem you must pre filter well before your water hits this or you'll have flow problem. A few hundred plastic pot scrubbers and filter socks does the trick in one system and filter wool in another. If you let it block with detritus you'll see its efficiency drop.
