About This

• PRE-RINSED & READY TO USE: The bio filter balls arrive pre-cleaned and ready for immediate installation. Simply place them in the included mesh bags and drop into your filter chamber — no scrubbing, no cloudy water, no waiting. Spend more time enjoying your aquarium and less time prepping filter media.
• OPTIMIZED POROUS STRUCTURE: Each 1-inch (26mm) bio ball features a multi-layered porous surface designed. The expanded surface area helps maintain water clarity. Engineered for reliable biological filtration performance.
• UNIVERSAL COMPATIBILITY: Whether you're running a freshwater community tank, a marine reef setup, a koi pond, or a turtle habitat — these bio balls work with ALL filtration systems: canister filters, wet/dry trickle filters, bottom filters, and pond filters. No compatibility guesswork needed.
• BUILT TO LAST: Crafted from premium safe material, the bio balls are designed for long-term submerged use without degrading, crumbling. Reusable and easy to maintain — just rinse gently with aquarium water (never tap water!).
• 200 PCS & 4 REUSABLE MESH BAGS: Each pack includes 50 bio filter balls (26mm diameter) plus 4 durable filter media bag for organized installation and easy removal during maintenance. Recommended for tanks 20-75 gallons. Pair with mechanical filter media (foam/sponge) as a pre-filter for ideal results — bio balls handle biological filtration while your pre-filter catches debris.
