The bio ball is manufactured from high-grade, non-toxic PP plastic structured into an engineered porous net configuration. Its internal porous matrix provides an extensive specific surface area designed for the dense colonization and rapid reproduction of beneficial nitrifying bacteria. This open framework actively promotes oxygen convection and efficient gas-liquid exchange during biological oxidation, establishing a stable and balanced aquatic ecosystem.
Houses an integrated filter cotton core, significantly enhancing microbial loading capacity and boosting overall biological filtration performance.
Porous net geometry accelerates convective oxygen exchange throughout the nitrification process, preventing anaerobic dead zones.
Provides a significantly greater surface area per cubic foot than conventional lava rock, increasing filtration volume without adding excess weight.
Scientifically calibrated shape evenly distributes water flow without jamming, channeling, or clogging the biological filter chamber.
Bio balls serve as an ideal biological media for trickle/drip filters, nitrate reduction reactors, biofalls, and large commercial aquaculture systems. Replacing lava rock in your biofalls with bio balls expands total biological capacity and maximizes water clarity.
Placement Positions: Upper trickle filter boxes, bottom sump compartments, lateral filter tanks, canister filters, and external bio-barrels.

They are constructed from advanced non-toxic polypropylene (PP) plastic, formed into a durable, porous net design safe for all aquatic environments.
Bio balls provide a significantly larger bio-surface area per cubic foot compared to lava rock, boosting biological load capacity, improving water flow, and avoiding the channeling common with heavy rock media.
The built-in filter cotton provides extra colonization space for beneficial nitrifying bacteria, substantially increasing the media's biological filtration density.
No. Their geometric design separates water flow uniformly, preventing debris compaction and media jamming while sustaining consistent aeration and nitrification.
They can be used across multiple setups including upper trickle filters, pond biofalls, sump bottoms, lateral filtration chambers, nitrate reactors, and external canister filters.
Bio balls with cotton are available in 16mm, 26mm, 36mm, 46mm, 56mm, and 76mm. Models without cotton come in 32mm, 42mm, and 48mm.
