Aquascape 53036 Large 21' x 26' Pond Kit – Complete Ecosystem System w/ AquaSurge 4000–8000 Pump

The Aquascape 53036 Large Pond Kit provides everything required to build a stunning 21' x 26' backyard pond with a fully adjustable flow system. Powered by the AquaSurge 4000–8000 Adjustable Flow Pump, this kit gives you digital control over waterfall and filtration flow rates, allowing you to easily fine-tune the look, sound, and performance of your pond.

This professional-grade kit includes Aquascape’s premium BioFalls® filtration, high-capacity skimmer, 45-mil EPDM liner, fittings, plumbing, and all necessary hardware for a long-lasting, high-performance pond system.

The electricity bill matters. Especially when a pond pump runs 24 hours a day, every day, for years.

That’s the core argument for the Aquascape 53036 and its AquaSurge 4000–8000 asynchronous pump. While the 9-PL Tsurumi pump (53037) draws approximately 1,000 watts continuously, the AquaSurge runs between 500 and 660 watts — depending on the flow setting you choose — while delivering up to 7,793 GPH when you need it. That’s roughly 40 to 45 percent less energy consumption for the same 21’ x 26’ ecosystem pond. Over a five-year pump life, that difference adds up to hundreds of dollars in electricity savings.

The 53036 builds the identical pond as every other Aquascape large kit: 21 feet by 26 feet, maximum depth of 2 feet, approximately 8,100 gallons of living, circulating ecosystem water. The Signature Series 1000 Skimmer provides mechanical filtration. The Signature Series 6000 BioFalls® delivers biological filtration and waterfall flow. The 25’ x 30’ / 45-mil EPDM liner and 750 sq. ft. of underlayment provide the structural foundation. The LED lighting package, Automatic Dosing System, and complete installation hardware round it out.

What the 53036 adds over the 53037 is app connectivity, adjustable flow control, and the AquaSurge’s asynchronous motor technology — the same motor architecture found in premium European variable-speed pumps. What it saves over the 53063 (SLD smart pump) is cost, while delivering equivalent water quality for ponds with standard head heights. And at a lower price than the 53067 Deluxe, it gives you the AquaSurge pump without the premium extras you may not need.

This is the smart-pump large pond kit for the builder who wants app control, energy efficiency, and a proven ecosystem system — without paying for features they don’t need.

Why Choose the Aquascape 53036 Large Pond Kit?

• Asynchronous motor technology — the efficiency difference. The AquaSurge’s asynchronous motor is fundamentally different from traditional direct-drive and magnetic-drive pumps. It provides higher torque at lower wattage, operates at lower temperatures (extending motor life), runs equally well in vertical or horizontal orientation, and maintains strong performance at higher head heights than equivalent mag-drive pumps. At 500–660W versus the 9-PL’s ~1,000W, the energy math is significant for a 24/7 continuous-duty application.
•  Full app control from your phone. Connect the included Smart Control Receiver to your home Wi-Fi, download the Aquascape Smart Control App (iOS and Android), and you can adjust pump flow, set on/off schedules, and monitor your system from anywhere. Turn the waterfall up when guests arrive. Dial it back overnight to reduce splash noise. Schedule seasonal flow changes without walking to the pond.
• Adjustable flow means one pump fits all scenarios. The AquaSurge doesn’t lock you into a fixed flow rate. From 4,000 GPH for quieter, lower-flow operation to 7,793 GPH at maximum output, you tune it to your waterfall height, pond volume, and aesthetic preference. This flexibility also means the pump remains appropriate as your pond’s needs evolve.
• Longer warranty than the 9-PL. The AquaSurge carries a 3-year limited warranty versus the 9-PL’s 2-year limited warranty. For a pump you’re running continuously, that extra year of manufacturer coverage is meaningful.
• Same complete kit. Identical ecosystem components to all other Aquascape 21’ x 26’ kits: BioFalls 6000 filter, Signature Series 1000 Skimmer, 25’ x 30’ EPDM liner, LED lighting, auto-dosing system, full installation hardware, and Welcome Kit. The pump is the differentiator. The ecosystem is the same.

What's Included In The Aquascape 53036 Pond Kit

Every component is pre-matched for a 21’ x 26’ / up to 2’ deep ecosystem pond:

Signature Series 1000 Pond Skimmer with Faux Rock Lid

Surface mechanical filtration — the first line of defense against debris. Skims leaves, pollen, and organic waste before they sink and decompose, while housing the AquaSurge pump inside a protected enclosure. The faux rock lid naturalizes the skimmer into the pond edge.

Signature Series 6000 BioFalls® Biological Filter with Rock Tray & BioBalls Media

The biological engine of the ecosystem. The BioFalls 6000’s large media surface area colonizes the beneficial bacteria that convert fish waste (ammonia and nitrites) into harmless nitrates, keeping water clear and fish healthy. The Rock Tray lets you naturalize the falls with fieldstone. The waterfall overflow simultaneously aerates the pond.

AquaSurge 4000–8000 Adjustable Flow Pump (SKU 45010) + Smart Control Receiver

Max flow 7,793 GPH. Asynchronous motor: 500–660W (adjustable), 5.5A, 28-foot max head, 20-foot cord. Operates in vertical or horizontal orientation. Rubber feet eliminate vibration and noise. Oil-free design prevents pond contamination. The Smart Control Receiver is included with the pump and enables Wi-Fi connectivity to the Aquascape Smart Control App — adjust flow, set schedules, and monitor the system remotely. 3-year limited warranty.

Complete LED Lighting Package

(2) 3-Watt LED Waterfall Spotlights, (1) 1-Watt LED Waterfall and Up Light, 60-Watt Transformer with photocell (auto on at dusk / off at dawn), 3-Way Quick-Connect Splitter, and 25 feet of LVL Extension Cable.

Automatic Dosing System for Ponds + Maintain for Ponds (32 oz.)

Set the dosing schedule once. The system automatically adds water treatments at your defined interval — beneficial bacteria and enzymes that prevent green water, reduce sludge, and maintain biological balance without manual intervention. The 32 oz. of Maintain for Ponds included starts your treatment routine immediately after filling.

25’ x 30’, 45-mil EPDM Fish-Safe Liner + 750 sq. ft. Geotextile Underlayment

The 25’ x 30’ liner builds a 21’ x 26’ pond at up to 2’ depth with proper edge overlap for anchoring and finishing. 45-mil EPDM is UV-resistant, fish-safe, and rated for 20+ years of continuous use. The geotextile underlayment cushions the liner against rocks and roots beneath.

2" x 50’ Flexible (Kink-Free) PVC Pipe

Connects the skimmer pump outlet to the BioFalls 6000 filter inlet. Kink-free construction accommodates bends in your pond layout without flow restriction.

Check Valve Assembly

Prevents backflow through the pump discharge line when the system is powered off, protecting the plumbing and preventing stream flooding on startup.

Installation Kit

Silicone sealant, EPDM liner patch, pond and waterfall foam sealant, PVC cement (Christy’s Red Hot Blue Glue), and all necessary fittings for a complete, leak-resistant build.

Welcome Kit

Introductory care guides, water treatment recommendations, and Aquascape ecosystem overview materials for new pond owners.

Which Aquascape Large Pond Kit Is Right For You?

All four Aquascape 21’ x 26’ large pond kits build the same pond. The pump is the differentiator:

The Energy Efficiency Advantage - What Asynchronous Technology Means

Most large pond pumps use direct-drive or magnetic-drive motor technology. Both are mature, reliable designs — but neither is optimized for variable-flow efficiency. When you run a conventional 1,000-watt pump at partial output, you’re still drawing close to full wattage.

Asynchronous motor technology changes this relationship. The AquaSurge’s motor scales power consumption with output demand. At minimum flow (4,000 GPH), the pump draws approximately 500 watts. At maximum flow (7,793 GPH), it draws approximately 660 watts. Compared to the 9-PL’s steady ~1,000 watts regardless of output, the AquaSurge’s efficiency advantage is most pronounced exactly when most homeowners run their ponds — at moderate, beautiful-sounding waterfall flow, not maximum output.

For a pond running 24 hours a day: the difference between 1,000W and 600W average draw is 400Wh per hour, or roughly 3,500 kWh per year. At the U.S. average electricity rate of ~$0.16/kWh, that’s approximately $560 per year in savings. Over the AquaSurge’s 3-year warranty period, that approaches $1,700 in energy cost difference — more than offsetting any price premium.
