Features: Bottom PumpTriple filtration function, mechanical, chemical and biological filtration; naturally circulate water flow to increase dissolved gas and oxygen content in water; suitable for both freshwater and seawater. Max. Flow RateMaximum Flow Rate: 2000L/H,high lift: 2m/6.56ft, high efficiency motor for energy saving. High-qualityMade of high-grade material, which is wear-resisting, non-toxic, safe to use. Quiet DesignThe reliable and durable motor does not make much noise, providing you a quiet environment. Built-in ChipTemperature control chip can prevent the water pump from being damaged by dry burning. Accessories2 nozzles(16mm/19mm) and 4m water tubing. The bigger nozzle, the bigger output; the smaller nozzle, the higher lift comparatively. The water pipe can connect the nozzle for drain water. Compact SizeThe exquisite size makes the pump easy to hide or disguise in the water. ApplicationsThis bottom filter submersible pump can be used for fish tanks, aquarium, fountain, hydroponic systems, cooling and circulation systems, etc. Specification: Plug Type: US/EU (Optional) Power: 35W/55W (Optional) Voltage: 110V (US Plug), 220V (EU Plug) , 50Hz Noise: 35dB Waterproof Grade: IPX8 Max.

Please check the voltage and power of the pump power before power on, insufficient power and insufficient frequency would affect the flow rate. 2. This pump can only be used in fresh water or sea water, and cannot be used in any other liquid. 3. The pump can't work in water above 35 degrees or below freezing point, otherwise it will be damaged. 4. DO NOT dry burn the pump for a long time, otherwise it would be damaged. 5. Please cut off the power before you install/put in/take away the pump from the water; otherwise, the pump can't outlet water due to the air in it. 6.
