Bio balls are an essential component for biological filtration in both aquariums and ponds. They provide a large surface area for beneficial nitrifying bacteria to colonise, which helps break down harmful ammonia and nitrites in the water.

Key Benefits:

  • Supports Water Quality: Nitrifying bacteria living on bio balls help maintain a healthy nitrogen cycle.

  • Stabilises pH: Bio balls can help keep pH levels near neutral over time.

  • Removes Harmful Ions: They can absorb and neutralise some poisonous ions, improving overall water quality.

  • Efficient Filtration: Provides a simple, effective way to enhance both biological and chemical filtration in your tank or pond.

Bio balls are compatible with most pond and aquarium filters, making them a versatile and effective addition.
