Description
The Atlantic-Oase 94629 Small Clear Water System Kit is a professionally engineered dual-pump pond ecosystem for 11'×11' ponds — delivering the Atlantic-Oase Clear Water Guarantee: crystal-clear water even with fish loads up to 10 inches per 100 gallons. Unlike standard single-pump pond kits, the 94629 deploys two pumps working in tandem: an Atlantic TT2000 surface pump feeding an SP1600 FastFalls spillway from the top, and an Oase AquaMax Eco Premium 2500 sitting on the pond floor, drawing fish waste and organic debris up from the bottom through the Oase filtration system. The result is clean-from-both-directions filtration that no single-pump system can match. The kit includes a 15'×15' 45-mil EPDM liner, 50 feet of 1.5" PVC, TR215CV check valve, AF1000 auto fill, and all installation hardware.
The Clear Water System Difference — Dual Pump vs. Standard Single-Pump Kits
Standard Atlantic PK pond kits use one pump housed in a skimmer, which circulates water from the surface through a FilterFalls biological waterfall filter. This works well for light fish loads and lower-maintenance ponds. The 94629 Clear Water System adds a second Oase pump on the pond floor, creating a completely different filtration dynamic:
| Feature | Standard Atlantic PK Kit (Single Pump) | 94629 Clear Water System (Dual Pump) ← |
|---|---|---|
| Surface debris | Atlantic Skimmer → FilterFalls | Atlantic Skimmer → TT2000 → SP1600 FastFalls |
| Bottom debris | Not addressed directly | AquaMax Eco Premium 2500 draws from pond floor |
| Filtration type | Biological waterfall filter (FilterFalls) | Oase multi-stage mechanical + biological (Eco Premium) |
| Winter operation | Standard pump, run dry at 32°F | AquaMax frost-safe to -4°F, Seasonal Flow Control |
| Fish load capacity | Standard light fish loads | Up to 10" fish per 100 gallons |
| Water clarity guarantee | No | Yes — Atlantic-Oase Clear Water Guarantee |

AquaMax Eco Premium 2500 — Oase's In-Pond Filter Pump
The AquaMax Eco Premium 2500 is the 94629 kit's defining component — the feature that separates the Clear Water System from every standard Atlantic pond kit. Sitting on the pond floor, it draws fish waste, organic debris, and suspended particles up from the bottom and delivers them to the Oase multi-stage filtration system. Key features buyers should know:
- Only 60 watts for 2,500 GPH. The AquaMax Eco Premium 2500 is one of the most energy-efficient solids-handling pumps at this flow rate — 60W moves 2,500 GPH, compared to many comparable pumps drawing 150–200W for similar output. Combined with the TT2000 at 115W, the entire dual-pump system draws just 175 watts total at peak.
- Seasonal Flow Control automatically reduces wattage up to 50% in winter. As water temperatures drop below 50°F, the AquaMax's Seasonal Flow Control progressively slows flow and cuts wattage — protecting beneficial bacteria in the filter media from being flushed during winter conditions and cutting operating costs without manual adjustment. The feature can be manually overridden if full flow is needed year-round.
- Frost-safe to -4°F. The AquaMax Eco Premium 2500 is specifically engineered to remain in the pond through winter without damage — down to -4°F. Most competitive pumps require removal and indoor storage when temperatures drop below 32°F. This pump stays in place year-round.
- Environmental Function Control (EFC) auto-shutoff. If the pump runs dry or gets blocked, EFC automatically shuts it off to prevent motor damage — then restarts when conditions are clear. No babysitting required.
- Second intake for optional satellite filter. The AquaMax Eco Premium 2500's second intake port accepts an optional Oase AquaMax Satellite Filter — allowing a second draw point at a different pond location, ideal for larger or irregularly shaped 11'×11' ponds.
- 5-year warranty (3+2 with product registration). Register your AquaMax Eco Premium 2500 at Oase for the full 5-year warranty coverage. The TT2000 carries a 3-year warranty. SP1600 FastFalls and Atlantic Skimmer enclosures carry a Lifetime warranty.

How many gallons does the 11'×11' Clear Water System pond hold?
An 11'×11' pond excavated to an average depth of 2 feet holds approximately 1,800 gallons (11×11×2 = 242 cubic feet × 7.48 = ~1,810 gallons). At 2.5 feet average depth, volume increases to approximately 2,265 gallons. The AquaMax Eco Premium 2500 provides full pond turnover roughly every 45 minutes at maximum flow — well above the recommended minimum of one full turnover per hour for clear water in fish ponds.
Why does this kit use two pumps instead of one?
The 94629 Clear Water System's dual-pump design solves a fundamental problem with standard single-pump pond kits: bottom waste accumulation. In a single-pump kit, the skimmer pump only pulls water from the surface — fish waste, organic debris, and uneaten food that sinks to the pond floor are left undisturbed, decomposing and releasing ammonia. The AquaMax Eco Premium 2500 sits on the pond floor and draws that bottom debris up through the Oase multi-stage filtration system, attacking the waste at its source. Combined with the TT2000 clearing the surface through the FastFalls spillway, you get top-to-bottom pond filtration that standard single-pump systems cannot deliver. This is why Atlantic-Oase can offer a written Clear Water Guarantee with this kit — the filtration architecture actually handles the full waste load, not just the surface.
Does the SP1600 FastFalls filter the water biologically?
No — the SP1600 FastFalls is a spillway diffuser, not a biological filter. It receives pumped water from the TT2000 and diffuses it over the 16" spillway edge to create a natural-looking waterfall. It has no filter media, no biological filtration chambers, and no mechanical filtration function. This is a key distinction from the standard Atlantic FilterFalls units used in the PK pond kit series. In the Clear Water System, all biological and mechanical filtration is handled by the Oase AquaMax Eco Premium 2500 bottom pump system — not at the waterfall. The FastFalls is purely decorative and aesthetic.
Can the AquaMax Eco Premium 2500 stay in the pond year-round?
Yes — the AquaMax Eco Premium 2500 is engineered for year-round in-pond operation and is frost-safe to -4°F. Its patented Seasonal Flow Control automatically reduces flow and wattage as water temperatures drop, protecting beneficial bacteria and reducing winter operating costs. Unlike most pond pumps that require removal and indoor storage below 32°F, the AquaMax Eco Premium 2500 stays in place through winter without damage. If ice forms over the pond surface, leave the pump running — circulation prevents complete surface freeze and maintains gas exchange for fish.
Is the 45-mil EPDM liner safe for fish?
Yes. The 45-mil EPDM liner included in the 94629 kit is fully fish-safe and is the industry standard for ecosystem pond construction. It remains flexible at temperatures as low as -40°F, resists UV degradation and ozone, and does not leach any chemicals that affect fish or aquatic life. The 12'×12' geotextile underlayment included in the kit provides puncture protection between the liner and the substrate. Note that the underlayment (12'×12') is smaller than the liner (15'×15') — the underlayment covers the interior pond footprint while the liner extends up and over the edges.
What does this kit ship with and how is it delivered?
The 94629 Clear Water System Kit ships via freight carrier. A $250 freight charge is applied at checkout. After the carrier receives your order, they will contact you to schedule a delivery appointment — typically requiring a 4-hour window. An adult 18 or older must be present to sign for delivery.
