Marine Pure Gems

Don’t let the name fool you — Marine Pure Bio Gems are suitable for freshwater, marine, and pond systems. Designed to support the removal of ammonia and nitrite in aquariums up to 75 gallons, this high-performance biological filter media provides the ideal environment for beneficial bacteria to thrive.

Engineered with advanced porous ceramic technology, Bio Gems deliver exceptional surface area for biological filtration while maintaining excellent water flow through the media — not just around it. This helps establish strong bacterial colonies that break down fish waste and contribute to cleaner, more stable water.

Why Choose Marine Pure Bio Gems?

• Helps reduce ammonia and supports lower nitrate levels

• Suitable for freshwater, saltwater, and pond systems

Thin Bio-Film Technology™
The open, interconnected pore structure encourages the growth of a thin, efficient bio-film, allowing nutrients to reach bacteria easily while preventing clogging. Old bio-film naturally sheds, keeping the media effective long term and ensuring water flows through the structure for maximum filtration performance.

Versatile Applications:

• Inside aquariums

• Sumps and wet/dry filters

• Canister filters

• Hang-on-back filters

• Trickle, shower, or waterfall filters

• DIY filtration systems

For cleaner, clearer water and powerful biological filtration, Marine Pure Bio Gems offer a simple and effective solution for a wide range of aquatic setups.
