Xport BIO Block 1.5" (4pk) Brightwell

Ultra-porous Biological Block Media with Superior Performance Characteristics

Overview

• 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 2” block has about 10,000 square feet of useable surface area for bacterial colonization, a 1.5” block has about 4,000 square feet of useable 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)
