Description

The Atlantic Water Gardens PK382025 Extra Large Pond Kit is a complete, professional-grade pond construction system engineered for ponds up to 16' x 21'. This kit includes everything needed to build a high-performing backyard pond with exceptional water clarity, strong circulation, and long-term reliability.

Featuring Atlantic’s industry-leading skimmer and BioFalls filter, premium EPDM liner, and a powerful energy-efficient pump, this kit is perfect for koi ponds, water gardens, and large landscape pond installations.

The Atlantic Water Gardens PK382025 is a complete, pre-matched 16'×21' pond construction system built around three lifetime-warranted or multi-year-warranted components: the BF3800 FilterFalls with a 38-inch spillway, the PS15000 Skimmer, and the TT9000 TidalWave3 asynchronous pump. Everything needed to build a functioning, fish-ready ecosystem pond is in one pallet-shipped box.

 

At 16'×21' with an average depth of 1.5 feet, this pond holds approximately 3,800 gallons — a volume that provides the thermal mass and dissolved-oxygen capacity that koi require. The TT9000 turns the full pond volume roughly every 1.5 hours at working head, which Atlantic sizes as appropriate for this kit's filter and skimmer combination.

 

The kit ships as a single pallet measuring 42"W × 36"H × 48"D. Every major component — pump, filter, skimmer, liner, underlayment, lighting, AutoFill, FallsFoam, check valve, tubing, fittings, and installation consumables — is included. Nothing is sold separately or requires a return trip to source.

Why Choose the Atlantic PK382025 Pond Kit?

  • BF3800 FilterFalls — 38" spillway with biological filtration chamber. Lifetime warranty on enclosure. This is Atlantic's largest single-unit FilterFalls, designed for high-volume pond systems with significant fish loads.
  • PS15000 Skimmer — removes surface debris before it sinks and decays, dramatically reducing anaerobic waste at the pond bottom. Lifetime warranty on enclosure. The PS15000 is Atlantic's premium large-format skimmer matched to the BF3800 at this flow rate.
  • TT9000 TidalWave3 Pump — asynchronous motor technology delivers up to 9,000 GPH at 587 watts. Asynchronous motors move significantly more water per watt than traditional direct-drive or mag-drive pumps. 20-foot power cord. 3-year warranty.
  • AF1000 AutoFill — automatically replenishes evaporation loss, protecting the TT9000 from running dry and keeping your waterfall at consistent height. Connects to a standard garden hose line.
  • Complete LED lighting package — (2) WWCS2 2-watt pond spotlights with 5-year warranty + WW30X4 30-watt transformer and splitter with 5-year warranty. Extends the visual enjoyment of the pond into evening hours.
  • 20'×25' 45-mil EPDM liner — fish-safe, UV and ozone resistant, rated for extreme cold. 20-year warranty. The liner is larger than the pond footprint to allow for proper edge finishing and rock placement.

Frequently Asked Questions:

What is included in the Atlantic PK382025 Extra Large Pond Kit?
The PK382025 includes: BF3800 FilterFalls (38" spillway, lifetime warranty), PS15000 Skimmer (lifetime warranty), TT9000 TidalWave3 pump (9,000 GPH, 587W, 3-year warranty), AF1000 AutoFill, (2) WWCS2 LED spotlights with WW30X4 transformer and splitter, 20'×25' 45-mil EPDM liner (20-year warranty), (2) 12'×25' heavy-duty underlayment panels, 3"×50' flexible PVC tubing, AWGCV30 3" check valve, (2) 12 oz. LF1100 FallsFoam, and an installation kit with fittings, thread sealant, and PVC glue. Everything ships on a single pallet.
What is the total water capacity of a 16' x 21' pond?
At an average excavated depth of 1.5 feet, the PK382025 kit supports approximately 3,800 gallons. This large water volume provides the thermal stability and dissolved-oxygen capacity that koi and large aquatic plants require. The BF3800 FilterFalls and PS15000 Skimmer are rated to process this volume continuously at the TT9000's flow rate, maintaining water quality under a healthy fish load.
How efficient is the TT9000 pump included in this kit?
The Atlantic TT9000 TidalWave3 is an asynchronous motor pump — it delivers up to 9,000 GPH at 587 watts. The asynchronous design moves significantly more water per watt than traditional direct-drive or magnetic-drive pumps of comparable flow, keeping 24/7 operating costs manageable on an extra-large pond system. The pump has a 2" MIPT inlet and a 2" FIPT / 3" MIPT outlet, a 20-foot power cord, and a 3-year warranty. It fits in tight skimmer vaults and can operate vertically or horizontally.
What is the BF3800 FilterFalls and how does it work?
The BF3800 FilterFalls is Atlantic's largest single-unit biological waterfall filter. It uses a biological filtration chamber to house beneficial bacteria that convert harmful ammonia and nitrites into less harmful nitrates — the same nitrogen cycle that keeps koi ponds healthy. The 38-inch wide spillway creates a wide, even waterfall curtain. The BF3800 enclosure carries a Lifetime warranty. Note: "FilterFalls" is Atlantic's product name; it performs the same function as Aquascape's BioFalls® but is Atlantic's own design.
Why is the AF1000 AutoFill kit included in the PK382025?
The AF1000 AutoFill connects to a standard garden hose line and automatically maintains pond water level as evaporation occurs. This is particularly important for high-volume pumps like the TT9000 — if the water level drops too low, the pump can run dry and be damaged. The AutoFill prevents this and keeps the waterfall flowing at consistent height without daily attention.
Is the 45-mil EPDM liner durable enough for winter climates?
Yes. The 20'×25' 45-mil fish-safe EPDM liner included in this kit remains flexible in extreme cold, resists UV and ozone degradation, and is rated fish-safe (no toxic off-gassing). It carries a 20-year warranty. The included heavy-duty underlayment cushions the liner against rocks and roots. The liner is sized larger than the pond footprint to allow for proper edge finishing, rock placement over the edges, and liner folding at corners without tension points.
Does this kit ship via freight?
Yes. The PK382025 ships on a single pallet measuring 42"W × 36"H × 48"D. Standard delivery is curbside — the carrier delivers to the curb or driveway. If you need inside delivery or a specific placement, please call us at (765) 508-4352 before ordering to discuss delivery options. Inspect the pallet carefully at delivery and note any damage on the carrier's delivery receipt before signing.
