Matrix is a highly porous, inert biomedia that houses the beneficial bacteria which break down aquarium waste. Its surface grows the aerobic bacteria that convert ammonia and nitrite, while the deep interior pores shelter anaerobic bacteria that reduce nitrate, so one media handles the full nitrogen cycle.
