Description
The EasyPro EPK1520 Eco-Series Complete Pond Kit includes everything needed to build a professional-grade 15'×20' backyard pond of approximately 3,400 gallons. The kit pairs the PS10E Ovation inside-liner skimmer (max 8,100 GPH) with the WF60E Symphony biofilter (up to 6,000 gallons — filter media included), driven by an EPA4500 asynchronous mag drive pump at 4,620 GPH. The complete 22'×25' 45-mil EPDM liner, check valve, 2"×25' flex PVC pipe, and PVC glue finish the system. All components are pre-matched and correctly sized — no separate sourcing needed.

Why the EasyPro Eco-Series EPK1520?
- PS10E Ovation's inside-liner installation eliminates the skimmer leak problem permanently. External skimmers are mounted on the outside of the pond liner with a faceplate that must be siliconed, bolted, and carefully sealed — a joint that can leak, loosen over time, and requires excavation to service. The PS10E installs inside the liner: the liner simply wraps into the skimmer opening and the soil backfill holds the skimmer in position. There is no penetration through the liner, no silicone joint to fail, and no tools required for installation. The patented design takes 15 minutes to set — vs. 2+ hours to properly seal and backfill a traditional external skimmer. For a DIY builder, this is the most stress-reducing component choice in the kit.
- EPA4500 at 4,620 GPH turns over 3,400 gallons approximately 1.4× per hour — correctly sized. The standard recommendation for ecosystem ponds is to turn over the total volume at least once per hour. At 4,620 GPH the EPA4500 achieves a 1.36× hourly turnover on the EPK1520's ~3,400-gallon pond — within the healthy range at actual operating head, where pump output drops below max. The asynchronous mag drive design is significantly more energy-efficient than direct-drive pumps at the same flow rate, and the epoxy-filled motor eliminates oil contamination risk.
- WF60E Symphony's 6,000-gallon rating gives the EPK1520 biological filtration headroom. Atlantic's BF1900 (included in comparably sized Atlantic kits) is rated to 1,900 gallons of pond volume — barely half the EPK1520's ~3,400 gallons. The WF60E Symphony is rated to 6,000 gallons — nearly double the pond volume it's actually filtering. This overhead is critical for koi ponds where fish bioload increases beyond initial stocking over time. The filter media shipping inside the WF60E (unlike Atlantic and EasyPro Pro-Series kits where media is extra) completes the biological zone immediately at startup.
- 22'×25' liner sizing is correct for a 15'×20' pond at 2' depth. The standard liner sizing formula adds twice the desired depth to each pond dimension, plus 2' of overlap around the perimeter. For a 15'×20'×2' pond: (15 + 2×2 + 2) = 21' width, (20 + 2×2 + 2) = 26' length. The 22'×25' liner is within this range — sized to allow proper liner draping without shortage at the corners. Verify final excavation dimensions before installation.
Frequently Asked Questions
What is included in the EasyPro EPK1520 Eco-Series 15'×20' Pond Kit?
The EPK1520 includes: 22'×25' EasyPro DuraLiner™ 45-mil EPDM pond liner, non-woven geotextile underlayment, PS10E Eco-Series Ovation Skimmer (inside-liner installation, max 8,100 GPH), WF60E Eco-Series Symphony Filter (up to 6,000 gallons — filter media and two filter pads included), EPA4500 asynchronous mag drive pump (4,620 GPH, 115V, 2-yr warranty), check valve assembly, 2"×25' flexible PVC pipe, PVC glue, and installation instructions. Ships approx. 260 lbs via motor freight.
How many gallons does the 15'×20' pond hold?
A 15'×20' pond built with the EPK1520 kit holds approximately 3,400 gallons at standard depth (confirmed by EasyPro authorized dealers). At 1.5' average depth the volume is approximately 3,366 gallons; at 2' depth approximately 4,488 gallons. This volume comfortably supports a healthy mix of koi and aquatic plants, providing ample thermal mass for temperature stability across seasons.
Is filter media included, or do I need to buy it separately?
Filter media is included in the WF60E Eco-Series Symphony Filter. Unlike EasyPro's Pro-Series AquaFalls™ kits and Atlantic Water Gardens pond kits — where biological media must be purchased separately — the Eco-Series Symphony Filter ships with media and two filter pads. No additional media purchase is needed to start the pond's biological filtration system.
How does the PS10E Ovation Skimmer installation work?
The PS10E uses EasyPro's patented inside-liner installation. The skimmer body is placed inside the pond excavation at the desired skimmer location. The pond liner is then draped across and into the skimmer opening — no holes are cut through the liner, no silicone is applied, and no bolts or tools are required. As the pond area is backfilled, the surrounding soil locks the skimmer in position. This design eliminates the penetration point that is the most common source of leaks in traditional external skimmers, and typically takes 15 minutes to set vs. hours for an external-mount installation.
What pump is included, and how energy efficient is it?
The EPK1520 includes the EPA4500 asynchronous mag drive pump producing 4,620 GPH at 115V. EPA series pumps use an asynchronous motor design — combining magnetic induction efficiency with direct-drive output — that consumes significantly less power than traditional direct-drive pumps at the same flow rate. The epoxy-filled motor housing contains no oil, eliminating contamination risk in the pond. 2-year manufacturer warranty.
Is this kit suitable for a koi pond?
Yes. The WF60E Symphony Filter is rated for ponds up to 6,000 gallons — substantially more headroom than the EPK1520's ~3,400-gallon pond. This filtration overhead is important for koi ponds where fish bioload increases as koi grow and multiply over time. The PS10E skimmer handles up to 8,100 GPH — well above the EPA4500's 4,620 GPH — ensuring debris is captured before it sinks. For a heavily stocked dedicated koi pond, consider adding a UV clarifier as an optional upgrade. Call us to discuss: (765) 508-4352.
How difficult is the installation of this pond kit?
The EPK1520 is designed for the serious DIY builder. All components are pre-matched and pre-sized — no guesswork in sizing the pump to the filter or skimmer. The PS10E Ovation's inside-liner installation is the simplest skimmer installation method available, requiring no silicone or tools. The WF60E Symphony's Spliner Lock system simplifies liner-to-filter attachment. A typical EPK1520 installation by two experienced DIY builders takes a full weekend (excavation on day one, liner and component installation on day two). Professional installation is also available through landscape contractors — call us for references: (765) 508-4352.
