Bio-Balls (26mm & 36mm) – Aquarium Biological Filter Media

Bio-Balls are highly effective biological filtration media designed to promote the growth of beneficial bacteria in aquarium filtration systems. Available in 26mm and 36mm sizes, these bio-balls provide a large surface area that helps break down harmful substances such as ammonia and nitrite, improving overall water quality.

The open-structure design allows excellent water flow and oxygen circulation, making them ideal for use in sump filters, wet/dry filters, trickle filters, and canister filters. By supporting strong colonies of nitrifying bacteria, bio-balls help maintain a stable and healthy environment for aquarium fish.

These durable plastic bio-balls are long-lasting, reusable, and suitable for both freshwater and marine aquariums.
