Why You’ll Love It
hygger aquarium 181 DC water pump delivers flexible, powerful, and quiet water flow control for aquariums, ponds, fountains, or hydroponic systems. With 10-speed flow control, two modes (steady and wave), dry-run protection, and anti-block features, it ensures safe operation. Available in multi-wattage models (28W to 92W/ 800-3170 GPH), this pump offers both high performance and adaptability, complete with a controller and multiple fittings included.
Key Features
10 Adjustable Water Flow & 2 Water Flow Modes
Normal mode (F1-F10) for fixed steady flow, wave mode for varying flow between the lowest and highest levels, each of which corresponds to a power level. The max power is the wattage of the pump model. The power display of wave-making mode 2 will change between the lowest and highest, because the waves are repeatedly changing progressively.
Strong Flow Rate & Wide Application
Precise control over water flow with ten gears and “wave mode” helps tailor the water movement to your specific aquarium or pond setup.
In normal mode, press the +/- key to adjust the gear, and the gear can be adjusted between F1 to F10.
Low Water Protection & Anti-blocking Function
Detects lack of water or block flow over 5 minutes, then automatically shuts off to prevent damage.
Anti-blocking function: when the pump is blocked, it stops running for protection after three blocked rotations are detected within 5 minutes.
5 Minutes Feeding Timing
Pause flow for 5 minutes to feed fish, then return to prior flow settings. Press the feed button, and the pump will display 0005, indicating that the feeding time is 5 minutes. When the feeding mode is over, the pump will run in the same gear as before feeding.
Quiet Operation Submersible DC pump
As a submersible pump, submersible 24V DC motor, ceramic shaft, magnetic drive, and vibration reduction designed for quiet use (~30 dB).
Controller & Multiple Fittings Included
Wired external controller, multiple nozzle adapters for different hose types, intake screens (normal & low water), O-rings, etc.
2 Ways to Use the Water Pump
Works submerged or external (inline), comes with multiple nozzle fittings and removable intake screens suited for varying water levels.
As a submersible pump, it can be fully immersed in water.
Common use cases:
Water Circulation: Moves water efficiently, ensuring proper circulation in ponds, fountains, or aquariums
Draining or Transferring Water: Can be used to drain pools, tanks, or flooded areas
Filtration Support: Works with filtration systems
Aeration: Helps oxygenate water
As an amphibious water pump, it can be placed out of water, with 2 hoses (not included) for connecting to 2 water sources.
Common use cases:
Reef Tanks: Provides essential water movement for coral health.
Freshwater Tanks: Ensures proper filtration and circulation.
Large Aquariums: Handles high water volumes efficiently.
Energy Efficiency
Using advanced intelligent frequency conversion technology, the power changes with the wave flow, which is more energy-saving. Its 10-speed gear and intelligent drive save power and extend the service life of the water pump.
Usage Tips
How to calculate GPH:
Water Pump Flow (GPH) = fish tank water volume (gallons) × number of cycles (5~10 times/hour)
- Install the pump fully submerged if using it internally; ensure the correct intake screen (low-water or normal), depending on water depth.
- Use the feed/pause function when feeding to stop the flow, then automatically return to the previous flow after 5 minutes.
- Choose a model based on both gallons per hour (GPH) and required head (height) so you get sufficient flow without overpowering or stressing aquatic life.
- Periodically check and clean intake screens/nozzles to prevent clogging and maintain optimal flow.
- If the pump is blocked or starts producing error codes (ER01, ER02, etc.), address those – clean propeller, reset with unplug/plug, ensure power is correct.
