Atlantic Water Gardens BF3800 Big Bahama FilterFall 38" Spillway

The Atlantic Water Gardens BF3800 Big Bahama FilterFall is a professional-grade biological waterfall filter designed to improve water clarity and support healthy pond ecosystems. Its 38" spillway produces a broad, natural cascade while the internal flow path and media remove suspended solids, convert ammonia and nitrites, and introduce oxygen to the pond water for healthier fish and plants.

• Waterfall width: 38" spillway delivers a wide, even curtain of water for a natural appearance.
• Dimensions: 46.5" W x 30" D x 23" H — compact footprint for a substantial waterfall effect.
• Pump flow range: 6,000–8,000 GPH recommended to activate the spillway and maintain effective filtration.
• Bulkhead: 3" bulkhead connection for secure plumbing attachment.
• Compatibility: Designed to match the PS9500 skimmer for integrated circulation systems.
• Included accessories: Installation kit, male thread adapter, and one-piece liner flange for faster setup.
• Expandable capacity: FilterFalls are engineered so filter volume can be increased as ponds age and biomass grows.

Built for reliable biological filtration and straightforward servicing, the BF3800 pairs generous flow capacity with accessible installation details to keep medium-to-large ponds clear and biologically balanced. Routine removal of coarse debris and periodic media checks will help maintain peak performance; consult the included Water Gardening Manual for full installation and maintenance guidance.

Choose the BF3800 when you want a broad, natural-looking waterfall combined with dependable biological filtration and the flexibility to expand filtration capacity as your pond ecosystem grows.
