What is MarinePure Block Bio Filter Media?

MarinePure Block Bio Filter Media is an incredibly porous, high performance biological media suitable for both freshwater and saltwater use. This Block variety is capable of removing ammonia, nitrite, and nitrate, and is designed to provide deep anaerobic zones for essential denitrification processes in passive or low flow systems. It’s best when used in an aquarium sump and it serves as a great alternative to live rock.

What are the benefits of MarinePure Bio Filter Media?

MarinePure is designed to be a substrate for bio-filtration, specifically to target ammonia and nitrite removal (nitrification) and to minimise nitrates (denitrification). It has a unique combination of large open pores and high surface area. This gives a large amount of bacteria easy access to nutrients (ammonia, nitrite and nitrate) and allows old bio-film to be easily flushed from the system. It can be used fully submerged or in trickle/shower filters (do not use in moving bed filters).
