Seachem Matrix is an advanced biological filtration media developed by Seachem to maximize biological filtration without the need for frequent replacement. It is engineered with an exceptionally high internal porosity, offering a vast surface area where beneficial bacteria can thrive.
This makes it an ideal choice for beginner aquarists who want reliable filtration with minimal maintenance, as well as experienced hobbyists looking to optimize water quality.
How Seachem Matrix Works
Matrix supports both aerobic and anaerobic bacteria:
-
Aerobic bacteria convert toxic ammonia into nitrite and then into nitrate.
-
Anaerobic bacteria, housed deep within the pores, help reduce nitrate levels naturally.
This dual-action process creates a more balanced nitrogen cycle, resulting in clearer water and healthier fish.
