·【Filtration Principle】

·①Impurities and dirty water are sucked away through the pipe with dirt suction, and water with oily on the water surface flows in through the oil film remover; ②Part of the impurities sink into the collection chamber and are discharged by opening 2 valves; ③Other Dirty water flows into the bottom container with filter material for filtration(not included).④Water pump in the bottom filter container runs (not included).⑤The filtered water flows into the tank through the upper water inlet pipe

·【External Fish Waste Separator】Double impurity collection chamber and double valve disposal switch design, double effect, can collect large particles of impurities separately, and quickly discharged. Suitable for tanks with large size or large number of fish, reducing filter cleaning and other tedious operations, and the replacement rate of filter media, improving the filtering effect.

·【Separator Operation】①Produces impurities and fish food waste; ②Sink to the bottom of the tank and be sucked away; ③304 stainless steel net intercepts part of the large-particle impurities; ④Then the large-particles go to the sedimentation box; ⑤ Rotating outlet valve to discharge water containing impurities.

·【External Hanging Filter Accessory】Compared with traditional fish tank PVC pipe, hygger aquarium overflow pipe no need to destroy the tank and drill holes. External hang on don't occupy internal aquarium space only 2 pipes in the fish tank. It is suitable for tanks that want a simple environment or fish that are afraid of the sound of the motor.

·【Product Advantages】Power outage and all operations stop. After power is restored, if the water pump can run, the filtration cycle will automatically start.The water outlet valve can adjust the water flow to avoid overflow.The hard pipe can be cut according to the height of the aquarium(cutting tool included).Contains pipe brush for easy cleaning. Comes with white tape to wrap around water leaking connections.

·【Recommendation】 Suitable for tanks larger than 20 gallons. Our fish waste collector filter have two separate parts -- water inlet and water outlet pipe fittings, and it needs to be used with an additional bottom container with filter media and water pump, is conducive to DIY filtration of long or large-sized aquarium. Freely match bottom tanks that can hold various types and quantities of filter materials.
