Pump comparison spotlight
Three widely sold submersible pumps from established pond brands, compared on their published figures.
| Pump | Type | Max flowat zero head | Max head | Power | Suited to | Keep in mind | Product link |
|---|---|---|---|---|---|---|---|
| Aquascape Ultra 800 | Submersible, magnetic drive | 793 GPH | 9 ft | 58 W | Small ponds, fountains and filter feeds with modest lift | Low 9 ft maximum head, so not suited to tall waterfalls | View on Amazon: Aquascape Ultra 800 |
| Aquascape AquaSurge 2000 | Submersible, asynchronous | 2,193 GPH | About 16 ft | 160 W | Medium ponds with a skimmer and a small to mid-size waterfall | Intended for skimmer or pump-vault installations; more pump than a small pond needs | View on Amazon: Aquascape AquaSurge 2000 |
| Atlantic-OASE TidalWave TT3000 | Submersible, asynchronous | 3,000 GPH | 19.5 ft | 173 W | Larger waterfalls and streams that need more flow at height | 1.5 in outlet: undersized tubing will throttle it | View on Amazon: Atlantic-OASE TidalWave TT3000 |
Figures are the published maximums, checked in October 2026 against Aquascape documentation (Ultra 800; AquaSurge flow and head) and current US retailer listings (AquaSurge power; TT3000 head and power). Retailers quote AquaSurge 2000 maximum head between 12.5 ft and 16.4 ft. Maximum flow is measured with no lift, so an installed pump delivers less: read the pump curve at your own head height, and confirm specifications on the current listing before you buy.

How Pond Pumps Adviser works
Research-based, and we say so
Guides are built from manufacturer manuals, published specifications and established hydraulic rules of thumb. We do not claim hands-on testing we have not done.
Sizing before shopping
Pond volume, target flow and head height come first, because those numbers decide whether a pump will actually do the job.
Clearly disclosed links
