Product information

Description

MARINA Aqua Natura TN-45165 Ø32 mm PP is a polypropylene bio ball cartridge designed as a replacement insert for compatible aquarium filtration systems. The cartridge provides a porous structure that increases surface area for colonization by nitrifying bacteria, supporting biological filtration and contributing to stable water parameters in freshwater tanks. Its 32 mm diameter and PP material make it suitable for routine cartridge replacement and simple maintenance.

Advantages

The bio ball insert is made from durable polypropylene, offering chemical resistance and stable porosity that resists compression over time. Its rounded bio ball geometry increases available surface area while maintaining high water flow-through, which helps sustain bacterial colonies that process ammonia and nitrite. Designed for easy insertion and removal, the cartridge simplifies routine maintenance without tools.

Suitable for

  • Replacement biological media in compatible aquarium filter cartridges with Ø32 mm fittings
  • Freshwater community and planted aquariums needing stable biological filtration
  • Routine aquarium maintenance and cartridge media refresh

Key specifications

  • Material: polypropylene (PP)
  • Shape: bio ball insert with porous structure
  • Diameter: 32 mm
  • Function: biological filtration media to support nitrifying bacteria
  • Compatibility: designed as a drop-in replacement for filters accepting Ø32 mm PP bio ball cartridges

How to use

Remove the existing cartridge from the filter according to the filter manufacturer’s instructions. Rinse the new bio ball insert briefly with conditioned aquarium water to remove dust from manufacturing; avoid using tap water with chlorine. Insert the cartridge into the filter housing ensuring a secure fit with the Ø32 mm opening, then reassemble the filter and restart it. Monitor water parameters after replacement to ensure biological balance re-establishes; do not wash the bio media aggressively to preserve beneficial bacteria.

Usage recommendations

Replace the bio ball cartridge as part of regular maintenance intervals recommended for your specific aquarium and filtration setup. When performing partial maintenance, stagger replacements to avoid sudden decreases in biological filtration. If possible, retain a small amount of old filter media to help reseed the new cartridge and shorten recovery time.
