The Velda Giant Biofill Sets are huge filters for heavily stocked fish ponds, designed to handle the increased bio-waste produced by your fish and the algae that can be caused by it. They include a Velda High Stream Pump and a Velda Silenta 300 air pump for added oxygenation.

They feature filters that have lift-out chambers that make it simple and easy to clean, reducing the time you are usually forced to spend performing essential maintenance.

The water is passed through the Biofill's four filter cassettes, each cleaning the water in different ways, including Japanese mats of different gradients to filter out larger dirt particles. The water also flows through a highly effective UVC to kill off and bind together free floating algae particles (the cause of green water), and also through the Bio Balls that make up the biological filter, breaking down toxins.

The filter has two ports to fit either external UVCs or heaters depending on your needs throughout the year, either heating the water in winter to protect your fish stock, or destroying more algae in the summer months where increased sunlight levels create larger algae blooms.

The water is passed through four filter cassettes. The first is meant for the UV-C Unit, the second is filled with bio balls, the third is equipped with a coarse Japanese mat and the fourth is filled with a fine Japanese mat.

The Silenta 300 Air pump is included as part of the fish care package - it pumps air to the bottom of your pond to increase oxygen levels in the water, allowing your fish to breathe more easily, especially in summer when hotter weather reduces these levels.

Please note these units do not include a plug
