CerMedia MarinePure Big Block - 20x20x10cm

CerMedia MarinePure Big Block 20 × 20 × 10 cm

CerMedia MarinePure Big Block provides a porous, inert home for beneficial bacteria that help remove ammonia and nitrite and lower nitrate in your aquarium. Its Thin Bio-Film Technology combines a large surface area with open, interconnected pores to maximise biological filtration.

Thin Bio-Film Technology

Water flows through the media rather than around it, making the internal surface area available for beneficial bacterial growth. Nutrients remain readily available to the thin biofilm, while old biofilm can be flushed from the open pores to help prevent clogging.

The block is primarily designed to provide deep anaerobic zones for denitrification in passive systems. It can also be used as a live-rock substitute for reef aquariums, supporting nitrate reduction without harvesting natural live rock.

Benefits

• High-performance biological filtration for value and a smaller filtration footprint.
• Helps reduce tank maintenance and supports higher fish loads.
• Helps maintain more consistent water chemistry.
• Inert media that will not harm aquarium inhabitants.
• Easy to shape to suit your filtration setup.

Applications

Use in sumps or stack in extra-large filters. MarinePure can also be used in the tank, canister filters, DIY filters, trickle or shower filters, waterfall filters and hang-on-back filters.
