Description
The Atlantic Water Gardens PK261520 Large Pond Kit is a complete, factory-matched ecosystem system for an 11'×16' pond — approximately 2,500 gallons at 1.5' average depth. The 15'×20' liner provides generous coverage for the pond basin plus depth and edge overlap. Every component is engineered and warranted by Atlantic Water Gardens: the TT5000 TidalWave pump (5,000 GPH) feeds through the PS7000 Skimmer to the BF2600 FilterFalls (26" spillway), with the AF1000 AutoFill maintaining water level automatically. LED lighting, FallsFoam, TR215CV Triton check valve, and installation materials are all included. Filter media is not included.

Why the Atlantic PK261520?
- TT5000 at 5,000 GPH — precisely matched to the 11'×16' pond. A 2,500-gallon pond needs at minimum full-volume turnover once per hour for effective biological filtration. The TT5000 at 5,000 GPH provides 2× the minimum turnover — enough for a strong waterfall display while giving the BF2600 FilterFalls adequate flow to sustain a robust bacterial colony for koi waste processing. The TT5000 is positioned between the TT4000 (PK191515, 11'×11') and TT6000 (PK262020, 16'×16') — Atlantic's middle-large pump selected specifically for the 11'×16' volume.
- BF2600 FilterFalls — 26" wide spillway, same as the PK262020. Despite being one size below the PK262020, the PK261520 shares the same BF2600 FilterFalls with its 26" spillway. This gives the 11'×16' pond a wide, dramatic waterfall that looks and sounds larger than the pond footprint alone suggests. The BF2600 houses biological filter media (purchased separately) in its internal chambers — the media basket is included, the media itself is not. Lifetime warranty on the enclosure.
- PS7000 Skimmer — mechanical first-stage filtration. The PS7000 pulls floating debris from the surface before it sinks and decomposes into muck. It houses the TT5000 pump, protecting it from large debris while drawing water from the surface. The PS7000's 7,000 GPH capacity exceeds the TT5000's flow rate — it will never be the flow bottleneck. Lifetime warranty on the enclosure.
- AF1000 AutoFill — prevents pump dry-run from evaporation. The AF1000 connects to a garden hose and automatically maintains pond water level as evaporation occurs. This is especially important during summer with the TT5000 running continuously — a pump running dry even briefly can cause motor damage. The AutoFill is a standard inclusion across Atlantic's medium and large pond kits.
- LED lighting — evening display built in. Two WWCS2 LED pond lights (12V, 2W each) with WW30X4 transformer and splitter are included. Additional lights can be added to the same transformer circuit with no additional hardware required. The lights are positioned during rock installation before surface stones are set.
- 15'×20' liner covers an 11'×16' pond with generous depth and edge allowance. The extra footage beyond the pond footprint accommodates excavation depth (2'+ on sides and bottom), plus a minimum 12-18" of liner extending past the pond edge on all sides for tucking, edging, and a waterfall lip. The 20-year liner warranty covers this 45-mil EPDM material for fish-safe long-term use.
Frequently Asked Questions
What is included in the Atlantic PK261520 pond kit?
The PK261520 includes: TT5000 TidalWave Pump (5,000 GPH, 3-year warranty), BF2600 FilterFalls (26" spillway, lifetime enclosure warranty), PS7000 Skimmer (lifetime enclosure warranty), TR215CV Triton Check Valve, AF1000 AutoFill, (2) WWCS2 LED pond lights + WW30X4 transformer, 15'×20' 45-mil EPDM liner (20-year warranty), 15'×20' heavy-duty underlayment, 2"×25' flexible PVC tubing, (2) 12 oz. LF1100 FallsFoam, fittings, thread sealant, and PVC glue.
Not included: Filter media for the BF2600 FilterFalls (purchase separately), stream liner if adding a waterfall run to the pond.
What size pond does the PK261520 create?
The PK261520 creates an 11'×16' pond — approximately 2,500 gallons at 1.5' average depth. Excavating to a 2' average depth increases volume to approximately 3,300 gallons. The 15'×20' liner is sized to accommodate the 11'×16' pond basin with additional footage for depth on all sides and edge overlap for finishing. The "15'×20'" refers to the liner dimensions — not the pond size. For koi, we recommend excavating to at least 2–3 feet in the deepest zone for thermal stability and predator protection.
How efficient is the TT5000 pump?
The TT5000 TidalWave pump delivers 5,000 GPH at 120V, drawing approximately 2.4 amps. The asynchronous motor design is engineered for continuous 24/7 operation with low operating costs compared to traditional direct-drive pond pumps. For a 2,500-gallon pond, 5,000 GPH provides 2× hourly turnover — well above the minimum recommended for koi ponds. The TT5000 carries a 3-year warranty.
Does the kit include filter media?
No — the BF2600 FilterFalls enclosure includes a media basket but no biological filter media. You will need to purchase filter pads, lava rock, ceramic rings, or bio-balls separately and add them to the FilterFalls before operation. Without media, the FilterFalls functions as a waterfall base only, not as a biological filter. Call us for compatible media recommendations: (765) 508-4352.
Can this pond kit support koi?
Yes. The BF2600 FilterFalls + PS7000 Skimmer creates the mechanical and biological filtration loop that supports koi. The PS7000 removes surface waste and debris before it sinks; the BF2600 processes dissolved ammonia through biological nitrification. For koi specifically:
- Excavate to at least 2–3 feet in the deepest zone for thermal stability and predator refuge
- Start with 2–3 medium koi in a 2,500-gallon pond at standard depth
- Add biological filter media to the BF2600 before adding fish — the bacterial colony needs 2–4 weeks to establish
- Monitor ammonia and nitrite weekly during the first month of operation
What does the AF1000 AutoFill do?
The AF1000 AutoFill connects to a standard garden hose and automatically refills the pond when the water level drops below a set point — compensating for evaporation and splash loss. This prevents the TT5000 pump from running dry (which can damage the impeller), maintains consistent waterfall flow, and eliminates the need for manual water level checks during hot summer periods when evaporation is highest.
Is stream liner included?
No — the 15'×20' liner covers the pond basin only. For a stream or waterfall run connecting to the pond, purchase stream liner separately. For medium and large kits like the PK261520, Atlantic recommends adding a 10'×15' boxed liner, 2"×25' tubing, and a 2" coupling to create a stream up to approximately 13 feet long. Call us to add stream materials to your order: (765) 508-4352.
