Xport BIO Blocks - 3.75cm - Biological Filtration Media - Brightwell Aquatics - 4 pack

Ultra-porous Biological Block Media with Superior Performance Characteristics


Designed to be used in marine and hard freshwater aquariums with a pH of 7.5 or over
Highest porosity and largest useable surface area, per unit weight or volume, of all filtration media available anywhere
Provides huge amounts of aerobic and anaerobic surface area for efficient bacterial colonization
Provides over 40,000 square feet (3,716 square meters) of surface area per liter of medium. One 5cm block has about 10,000 square feet of useable surface area for bacterial colonization, a 3.75cm block has about 4,000 square feet of usable surface area
When properly colonized, and used as directed, they will reduce toxic ammonia and nitrites to near zero in ponds and all aquariums, marine or fresh
Also reduces phosphate significantly and dissolved organics
Works excellently as the only filtration medium for the aquarium or pond or may be employed in addition to other filtration media
Doped with Aragonite to buffer pH at the bacteria level, preventing acid buildup which eventually would kill the bacteria and reduce capacity. (Which is what happens in competing products)
