The BF1600 Oasis FilterFall provides reliable biological and mechanical filtration while creating a natural 16" waterfall. Built to integrate with stone or stream features, this unit gives pond owners a compact, serviceable biofilter with easy liner attachment and room for upgradeable media.

  • Spillway Width: 16" engineered spillway for consistent waterfall flow.
  • Recommended Pump Flow: 1,000–3,900 GPH to match waterfall height and filtration needs.
  • Bulkhead: 1.5" FIPT bulkhead included; additional sizes available separately.
  • Dimensions: 21.5" W x 19.5" D x 17.75" H — compact footprint for small to medium ponds.
  • Capacity: Sized for ponds up to approximately 1,250 gallons with space for extra media.
  • Included Accessories: removable top grate, male thread adapter (MTA), media bag, stainless hardware, one-piece liner flange and fish-safe silicone.

FilterFalls use an upflow design to remove suspended solids, support beneficial bacteria that convert ammonia and nitrite to less harmful nitrates, and aerate pond water. The reinforced polyethylene enclosure and support bars let you camouflage the unit with rock while keeping routine maintenance simple — lift off the grate, rinse mats or replace media as needed. Match the BF1600 with Atlantic skimmer model PS3900 for balanced surface skimming and filtration. Follow the supplied installation manual for secure liner attachment and plumbing; use the included MTA and supplied instructions to ensure a watertight seal.
