Frequently Asked Questions
These porous plastic bio-balls serve as biological filter media in aquariums and pond filters. Their porous structure provides a large surface area for beneficial bacteria to colonize, which processes ammonia and nitrite through the nitrogen cycle — essential for maintaining safe water chemistry in any fish-keeping setup.
Each pack contains 20 pieces. The 20-piece quantity is a starter amount suitable for smaller nano tanks or as a supplement to existing filter media in a medium-sized aquarium. For larger aquariums with higher bioloads, multiple packs can be combined to increase biological capacity.
These balls are available in six sizes: 16mm, 26mm, 36mm, 46mm, 56mm, and 76mm. Smaller sizes (16–26mm) are suited for compact internal filters and nano tank setups, while larger sizes (46–76mm) are used in external filters, sumps, or pond filtration systems with larger media chambers.
The porous surface dramatically increases the effective surface area per unit volume compared to solid media. A porous 36mm ball may provide several times more colonizable surface area than a solid ball of the same size, which translates directly into higher biological filtration capacity per liter of media.
Yes, the plastic construction is chemically inert and resistant to saltwater corrosion. Bio-balls are used in both freshwater setups and marine systems, including reef aquariums and fish-only marine tanks, where they serve as the primary or supplementary biological filtration media.
New bio-balls can be placed directly into a filter without special preparation. However, colonization by beneficial bacteria takes time — typically 4–6 weeks in a new tank before the nitrogen cycle is fully established. Seeding with established bacterial products can accelerate this process significantly.
