Bio Balls with Sponge Aquarium Biological Filter Media (per piece)

Description

These plastic Bio Balls with integrated bio-sponge are a versatile and long-lasting biological filtration media suitable for all types of aquarium filter systems. Each 36mm ball combines a structured plastic frame with an internal sponge layer, providing significantly greater effective surface area than plain plastic bio balls, supporting larger and more stable populations of beneficial bacteria.

• 36mm bio balls with integrated sponge — more surface area than standard plastic balls alone
• Removes toxic ammonia and nitrite through biological nitrification
• Safe for freshwater and marine aquariums including reef tanks and coral systems
• Lightweight but durable and shape-retaining — will not degrade or compact over time
• Can be used loose or in mesh bags for flexible filter placement
• Low maintenance — rinse gently in aquarium water only if biofilm becomes excessive
• Sold per piece — build up your media volume at your own pace

Bio balls are a staple of aquariums filtration, particularly in sump-based and trickle filter systems where their open structure allows excellent water-air contact. The addition of internal sponge in this design makes them significantly more effective than plain plastic bio balls at supporting nitrifying bacteria populations. Suitable for cichlid tanks, community freshwater setups, and marine reef sumps.
