These gems measure approximately ¾ inches in diameter and are packaged in 90g hexagonal boxes. Each box offers an outstanding 1,450 square feet of accessible surface area, making them a powerful option for effective bio-filtration in systems up to 70 gallons. The MarinePure Bio Filter Gems facilitate ammonia and nitrite removal while optimising water quality by reducing nitrates.

Designed for versatility, these gems fit perfectly in various filter types, including canister filters, hang-on-back filters, and nano-tank systems. Made from inert materials, they are aquarium-safe and promote the growth of beneficial bacteria crucial for maintaining a healthy aquatic environment.

The Thin Bio-Film Technology ensures optimal conditions for bio-film development, with interconnected pores encouraging nutrient access and the natural flushing of old bio-film. This enables a maximised use of surface area for bacteria colonisation, effectively enhancing water purification processes.
