Description
The Atlantic Water Gardens PK191520 Medium Pond Kit delivers everything needed to build a complete, professionally designed 11'×16' backyard ecosystem pond of approximately 2,000–2,500 gallons. Anchored by a TT5000 TidalWave 3 pump at 5,150 GPH, the kit pairs the PS4600 Big Bahama Skimmer with the BF1900 FilterFalls™ — both backed by Lifetime Warranty — and includes a 15'×20' 45-mil EPDM liner, AF1000 Auto Fill, LED pond lights, TR215CV Triton Check Valve, FallsFoam, and a full installation hardware kit. Pre-matched components eliminate guesswork. All filtration is properly sized for the 11'×16' pond footprint.

Why the Atlantic PK191520?
- TT5000 TidalWave 3 — 5,150 GPH at 310W is exceptional efficiency. Atlantic's TidalWave 3 asynchronous pumps combine magnetic induction efficiency with direct-drive geometry. The result: the TT5000 delivers 5,150 GPH using only 310W — that's over 16 GPH per watt. Comparable direct-drive pumps at the same flow rate typically consume 500–700W. Running 24/7 at 310W costs approximately $27/month at the national average electricity rate — a meaningful operating cost advantage on a feature designed for continuous operation. The asynchronous motor is also notably resistant to hard water fouling, a common cause of pump failure in pond applications.
- PS4600 Big Bahama Skimmer — sized correctly for 11'×16' at 400 sq.ft. coverage. The PS4600 carries a 400 sq.ft. pond surface area rating — fully adequate for the 176 sq.ft. surface of an 11'×16' pond, with headroom for a future pond extension. The Super Flow weir door maximizes skimming at the pump's 5,150 GPH flow rate without allowing water to bypass. The heavy-duty brush panel and stainless framed trap net provide two-stage mechanical filtration inside the skimmer box, reducing the load on the downstream BF1900. The lid supports natural rock camouflage and foot traffic — no unsightly plastic visible above grade.
- BF1900 FilterFalls™ — 19" waterfall spillway and biological filtration in one unit. The BF1900's three-zone filtration system — filter pad zone, media zone, and swirl chamber — creates multiple opportunities for beneficial bacteria to colonize and process ammonia and nitrites. The 19" spillway width creates an attractive, wide-sheet waterfall that is audible from a comfortable distance. The enclosure's liner attachment flange seals the falls to the EPDM liner, preventing bypass leakage. Both the PS4600 and BF1900 carry Atlantic's Lifetime Warranty on the enclosure — the most important structural components of the system are warranted indefinitely.
- AF1000 Auto Fill eliminates the most tedious daily maintenance task. A properly aerated pond in summer heat loses 1"–2" of water per week to evaporation. Without an auto fill, owners must manually add water multiple times per week or risk exposing the pump to dry-run conditions. The included AF1000 maintains water level automatically — it mounts to the skimmer and connects to a garden hose, opening when the water drops and shutting off when the level recovers. Set it once, forget it for the season.
- LED lighting is included — not an afterthought add-on. The (2) WWCS2 LED pond lights and WW30X4 transformer/splitter allow evening illumination of the waterfall and pond from day one. LED pond lights extend the usable hours of the water feature dramatically — the sound and visual of a backyard waterfall at night is a fundamentally different experience than daytime viewing. Upgrading to lighting after the pond is built requires draining sections or threading cable under rocks; the fact that the wiring harness is included in the kit eliminates that retrofit headache.
Frequently Asked Questions
What is included in the Atlantic PK191520 Medium Pond Kit?
The PK191520 includes: 15'×20' 45-mil EPDM pond liner (20-yr warranty), heavy-duty underlayment, TT5000 TidalWave 3 pump (5,150 GPH, 310W, 3-yr warranty), PS4600 Big Bahama Skimmer (Lifetime warranty on enclosure), BF1900 FilterFalls™ (19" spillway, Lifetime warranty on enclosure — filter media NOT included), TR215CV Triton Check Valve, AF1000 Auto Fill, 2"×25' flexible PVC tubing, (2) WWCS2 LED pond lights with WW30X4 transformer and splitter, (2) 12 oz. LF1100 FallsFoam, and a complete installation kit with fittings, thread sealant, and PVC glue.
How many gallons does the PK191520 pond hold?
The PK191520 creates an 11'×16' pond footprint holding approximately 2,000–2,500 gallons, depending on excavation depth. At 18" average depth the pond holds roughly 2,000 gallons; at 24" average depth approximately 2,500 gallons. This volume comfortably supports a healthy mix of aquatic plants and goldfish, and is suitable for moderate koi stocking. For heavily stocked koi, consider the larger PK261520 (upgraded PS7000 skimmer and BF2600 FilterFalls™) or call us for sizing guidance: (765) 508-4352.
What pump is included and how energy efficient is it?
The PK191520 includes the Atlantic TT5000 TidalWave 3 pump — 5,150 GPH max flow at 310 watts, 120V, 2.7 amps, 20' power cord. The TidalWave 3 is an asynchronous pump that combines magnetic induction efficiency with direct-drive output, delivering more GPH per watt than traditional direct-drive designs. Running continuously at 310W costs approximately $27/month at the national average electricity rate. The TT5000 carries a 3-year limited warranty and is specifically selected by Atlantic to match the flow capacity of the PS4600 skimmer (max 4,000 GPH) at operating head height.
Does the BF1900 FilterFalls include filter media?
No — filter media is not included. The BF1900 FilterFalls™ ships with a media bag, filter pad, removable grate, and liner attachment flange — but the biological filter media fill (lava rock, bio-balls, or equivalent) is not included and must be purchased separately. Lava rock is the most common choice — plan for 40–60 lbs to fill the BF1900's media zone. This media provides surface area for beneficial bacteria colonies that biologically process fish waste. Call us for media recommendations: (765) 508-4352.
What is the difference between the PK191520 and the PK261520?
Both kits create an 11'×16' pond with a 15'×20' liner. The key difference is the filtration system: the PK191520 uses the smaller PS4600 skimmer (400 sq.ft., 6" weir) paired with the BF1900 FilterFalls™ (19" spillway) and a TT5000 pump (5,150 GPH). The PK261520 upgrades to the larger PS7000 skimmer paired with the BF2600 FilterFalls™ (26" spillway) and a TT5000 pump. The PK261520's wider waterfall and higher-capacity skimmer make it better suited for koi ponds with heavier fish loads. The PK191520 is ideal for water garden and ecosystem pond builds with mixed plant and fish populations. Call us to discuss which is right for your planned fish stocking: (765) 508-4352.
Is this pond kit suitable for koi?
Yes, at moderate stocking levels. The PS4600 skimmer removes surface debris continuously before it decays and produces ammonia, while the BF1900 FilterFalls™ biologically processes fish waste through beneficial bacteria in the media zone. The TT5000 at 5,150 GPH turns over a 2,500-gallon pond approximately twice per hour — adequate for light to moderate koi stocking. For a dedicated, heavily stocked koi pond (more than one inch of koi per 10 gallons), the PK261520 or PK262020 with the larger BF2600 FilterFalls™ would provide more filtration headroom. Call us for a free pond sizing consult: (765) 508-4352.
How is the Atlantic 45-mil EPDM liner different from PVC pond liner?
The 45-mil EPDM liner included in the PK191520 is significantly superior to PVC alternatives for permanent installations. EPDM (Ethylene Propylene Diene Monomer) remains highly flexible even at sub-zero temperatures — it won't stiffen, crack, or become brittle in cold climates. It is UV-resistant, fish-safe (confirmed non-toxic to aquatic life), and conformable to irregular excavation shapes without seam stress. Atlantic's 45-mil thickness provides substantial puncture resistance when paired with the included heavy-duty underlayment. The liner carries a 20-year warranty — PVC liners typically carry 5–10 years and begin showing UV degradation within a decade in sun-exposed installations.
