Feature:

• DC voltage,wave makers
  are driven by either DC12V or DC24V, which is rated for human and fish
  safe. sine wave technology, super quiet <20dB

• 
  

• Super compact and
  powerful. The size is barely 1.5" long. You can easily hide the wave maker
  anywhere in the tank without being seen.

• 
  

• New patented stator
  design, it pushes 1585 GPH to 6604 GPH (model dependent)

• 
  

• 3 wave
  attachments: 1) wide angle: for making large and gentle current; 2)
  medium: for making moderate water movement and mid-range distance; 3) narrow:
  strong jet-like current and long distance

• 
  

• Six pre-set wave
  patterns. Each wave pump comes with four pre-set wave modes: Classic Wave,
  
  Nutrient Transmission Wave, Constant Stream, and Random Wave. 

• 
  

• 10-level of flow
  rate/intensity adjustment for different tank sizes. Pump angle is also
  adjustable

• 
  

• Alloy motor isolation
  design prolongs the life

• 
  

• Durable, corrosion
  resistant

• 
  

• High flow rates, no
  attenuation

• 
  

• Bluetooth built-in
  controller

Note:

• How to turn on/off the Bluetooth app mode?    

       Long press the
mode button to turn on/off app mode. The blue light flashes indicating the

device enters the app mode. Solid Bluetooth led indicates the app is 
connected to the phone app

• How to change wave mode?

       In controller,
short press mode button, you can switch the wave mode between: Constant wave,
Pulse wave, and device powering off.

• How to adjust the flow rate/intensity?

       Press the
intensity button one at a time, the intensity will toggle between levels 1-10.
1 Intensity LEDs will be turned on/off per 2 level increased/decreased.

• How to connect the app on the phone?

       On the phone app,
search for AQUA ZKSJ; download it and install it on the phone.

slim 2000 and 3000, these two models are without Bluetooth control.
