Giant Biofill XL Multichamber Filter for Koi Ponds

The Giant Biofill XL is a high-capacity multichamber filter system designed to improve water quality and support a healthy environment in koi ponds. With its layered filtration process and integrated UV-C unit, it efficiently removes debris, breaks down waste, and combats floating algae for consistently clear, clean water.

Water is directed through multiple chambers, flowing up and down through filter cassettes filled with Japanese matting and bio filter media. This design allows for extended contact time and thorough filtration, ideal for larger ponds with heavy fish loads.

Key Features:

• Multichamber design promotes thorough biological and mechanical filtration
• Integrated 18W UV-C unit controls algae and harmful bacteria
• Supplied with Japanese matting, bio filter balls, and all connection fittings
• Optional add-ons include internal aeration and pond heater for year-round use
• Available as a complete set with pump, UV, hose, and adapters
• Dimensions: 60 x 80 x 60 cm

Installation is straightforward—simply connect to a dirty-water pond pump, attach a filter hose, and position the filter next to the pond. Once the pump and UV-C unit are plugged in, the system begins to work immediately. Routine maintenance is easy thanks to the accessible cassette design.
