Ziss ZB-300F Moving Bed Filter
The Ziss ZB-300F is a highly efficient air-driven moving bed filter designed to provide excellent biological filtration, strong oxygenation and reliable water movement from one compact unit.
The F model is the flow-enhanced version of the Ziss Bubble Bio range. Its adjustable outlet helps create additional circulation through the aquarium, making it particularly useful in breeding, grow-out and heavily stocked tanks where both biological filtration and good water movement are important.
Inside the filter, 300ml of Ziss ZM-II moving media is kept continually in motion by the airflow. This provides a highly oxygenated surface for beneficial bacteria, while the constant movement helps keep the media self-cleaning. A sponge pre-filter at the base also provides mechanical filtration by catching larger particles before water reaches the biological chamber.
Suitable for aquariums up to 300 litres, the ZB-300F is approximately 26–27.7cm tall and 7.5cm in diameter.

Why We Like It
The ZB-300F combines the biological capacity of a moving bed filter with useful additional water movement, all without needing an electrical filter inside the aquarium.
It’s particularly well suited to fish-room setups and breeding tanks, where simple, dependable filtration that’s easy to maintain makes a real difference.
