Bio-Balls are an effective way to strengthen your pond’s biological filtration. With their high surface area design, they create ideal conditions for colonies of beneficial bacteria that break down harmful compounds and support clear, healthy water.

Lightweight and durable, these 1.5" spheres are easy to clean and resist clogging. Their rounded shape reduces channeling, ensuring even water distribution throughout the filter chamber.

Why Choose Atlantic-Oase Bio-Balls?

  • High surface area: Each ball provides nearly 25 sq in for beneficial bacterial growth.
  • Durable and lightweight: Built to last without adding excess weight to the filter.
  • Easy maintenance: Simple to rinse and reuse during routine cleaning.
  • Reduced channeling: Spherical design prevents water bypass for better filtration.
  • Versatile use: Ideal for FilterFalls and other biological filtration systems.

PRO TIP

For best results, use Bio-Balls in a media bag inside your FilterFalls. This makes it easy to remove them for rinsing without disrupting beneficial bacteria colonies.
