Description
The EasyPro ET66FB Pro-Series Mini Pond Kit provides everything needed to build a professional-grade 6'×6' backyard pond in a weekend — approximately 400 gallons at 2' depth. This is the smallest kit in EasyPro's Pro-Series lineup, using the same contractor-grade components as their larger kits scaled for compact spaces: a PSMFB Mini Skimmer with filter brushes (not foam pads), an AT Mini AquaFalls™ biological waterfall filter with molded rock lip, and a TLS1850 Spirit Pump (1,850 GPH, 260W direct drive). All wrapped in a 10'×10' 45-mil EPDM fish-safe liner with a 20-year warranty. Ships via UPS or FedEx — no freight required.

Why Filter Brushes Beat Foam Pads for Small Ponds
The PSMFB Mini Skimmer uses filter brushes instead of the foam mats found in entry-level big-box kits. Foam mats trap fine debris but clog quickly, reducing water flow to the pump and requiring frequent scrubbing. EasyPro's filter brushes catch leaves, sticks, and larger debris while allowing water to pass through freely. Monthly rinsing is typically all that's needed. For a 6'×6' pond that may be surrounded by trees or landscaping, a low-clog filtration system makes a meaningful difference in weekly maintenance time.
ET66FB Mini vs. ES66FB Small — What Changes If You Upgrade
| Feature | ET66FB Mini (this kit) | ES66FB Small (upgrade) |
|---|---|---|
| Pond / Volume | 6'×6' — ~400 gal. | 6'×6' — ~400 gal. (same footprint) |
| AquaFalls Filter | AT Mini — 18"L×24"W×18"H | AS Small — larger capacity |
| Pump | TLS1850 direct drive — 1,850 GPH; 260W; 18-mo warranty | Higher-capacity pump; 3-year warranty |
| Tubing | 1.25"×25' | 1.5"×25' (larger diameter) |
| LED Lighting | Not included | 3 mini LED lights + 45W transformer — included |
| Beneficial Bacteria | Not included | Included |
| Price Difference | Lower cost | ~$200-$300 more — adds lights, better pump warranty, larger filter |
Both kits build the same 6'×6' pond. The ES66FB is worth the upgrade if you want LED lighting from day one, a 3-year pump warranty instead of 18 months, and a larger filter capacity for heavier fish loads. Call us to discuss which is right for your planned pond: (765) 508-4352.
Installation Tips for the ET66FB
- Location: Avoid low spots where runoff collects. 4–6 hours of sunlight supports healthy aquatic plants. Keep away from large trees to reduce leaf load on the skimmer.
- Excavation: Dig a 6'×6' area with a plant shelf 8–10" deep around the perimeter. Then excavate the center deep zone to 18–24". This creates natural planting shelves for marginal plants and water lilies.
- Bio-media first: Add bio-balls or lava rock to the AT Mini AquaFalls filter before filling the pond. The AT ships without bio-media — you need it for biological filtration to function from day one.
- Bacteria startup: Add beneficial bacteria at fill. Without it, expect 2–6 weeks of green water while the nitrogen cycle establishes.
- Waterfall foam: EasyPro Black Waterfall Foam (sold separately) is needed to seal the liner around the AT AquaFalls opening. Have it on hand before installation day.
Frequently Asked Questions
What is included in the EasyPro ET66FB Mini Pond Kit?
The ET66FB includes: 10'×10' 45-mil EPDM rubber liner (20-year warranty), 10'×10' underlayment, PSMFB Mini Skimmer with filter brushes, AT Mini AquaFalls™ biological waterfall filter with molded rock lip (filter pads included; bio-media NOT included), TLS1850 Spirit Pump (1,850 GPH, 260W, 16' cord, 18-month warranty), 1.25"×25' PVC flex pipe, 1.25" check valve assembly, and silicone sealer + PVC glue.
Not included: biological filter media (bio-balls, lava rock), beneficial bacteria, waterfall foam sealant (all sold separately), LED lighting, and rocks/gravel.
How many gallons does the ET66FB pond hold?
The ET66FB builds a pond approximately 6 feet by 6 feet, holding roughly 400 gallons at 2-foot depth. Digging to 24" is recommended for goldfish over-wintering and thermal stability. The pond volume suits a modest goldfish and aquatic plant ecosystem; for koi, 24" depth and conservative stocking are important starting points.
Why does the AT Mini AquaFalls not include bio-media?
EasyPro ships the AT Mini AquaFalls with filter pads and a media bag — but not the biological media that fills the bag. This is consistent across the Pro-Series AquaFalls line. Different pond builders prefer different media types (bio-balls, lava rock, Matala pads), so EasyPro leaves the choice to the installer. For this 6'×6', 400-gallon pond, a small bag of bio-balls or 5–8 lbs of lava rock is a suitable starting load. Have your bio-media ready before filling the pond. Call us for media recommendations: (765) 508-4352.
What is the TLS1850 pump, and is it a mag drive pump?
The TLS1850 Spirit Pump is a direct drive submersible pump — not a mag drive. Direct drive pumps use an impeller mounted directly on the motor shaft, delivering strong, consistent flow. The Spirit series is Italian-engineered, oil-less, and fish-safe. Key specs: 1,850 GPH max flow; 115V; 260W; 16' power cord; 1.25" FPT outlet. The pump carries an 18-month warranty. It can be run vertically or horizontally, making it well-suited for placement inside the PSMFB Mini Skimmer.
Is this kit suitable for koi?
The ET66FB is workable for a small number of koi — typically 1–2 small koi under 8" — but is generally better suited to goldfish and aquatic plants. Koi produce significantly more waste than goldfish and can grow 12–18"+ at maturity, quickly outpacing a 400-gallon pond's filtration capacity. If koi are your priority, the ET66FB is the minimum viable kit; excavating to the full 24" depth and keeping fish density low are important. A UV clarifier add-on is also worth considering for koi water quality. For a koi-focused build, the ES66FB Small Kit (larger filter, better pump warranty) or an 8'×11' kit provides more filtration headroom.
What is the difference between the ET66FB Mini and the ES66FB Small kit?
Both kits build a 6'×6' pond. The ES66FB Small Kit upgrades several components: a larger-capacity Small AquaFalls filter (AS model), a more powerful pump with a 3-year warranty (vs. the ET66FB's TLS1850 at 18 months), 1.5" tubing (vs. 1.25"), three mini LED lights with 45W transformer, and a starter pack of beneficial bacteria. The price difference is typically $200–$300. The ES66FB is worth considering if you want LED lighting from the start, a longer pump warranty, or a slightly larger filtration buffer for heavier fish stocking. The ET66FB is EasyPro's entry-level Pro-Series option — a professional-grade kit at a more accessible price point.
