2 in 1 multi-function cleaner: The gravel cleaner is very suitable for water change and sand washing. The large diameter suction pump has a built-in round hole filter to prevent the suction of small fish and gravel. Effectively removes feces and food from the tub, and the residue is separated to ensure the freshness of the water. High quality material: This aquarium water dispenser is made of plastic of high quality and can be used for a long time. Soft and transparent PVC hose can transfer fluid faster. All materials exist separately, can be disassembled by themselves, and are easy to clean. At the same time, disassembly and assembly are simple and easy to carry. Easy to use: The siphon pump is easy to grip. Just squeeze the pump a few times and the water will flow out automatically. High quality PVC pipes will not collapse and therefore will not block the flow of water. (Note: The position of the water outlet should be lower than the position of the water inlet.) Control valve design: The water flow can be adjusted through the control valve, and the water flow can be controlled at will according to the actual situation, which is more conducive to cleaning. Multi-function: The self-priming water diversion design small and exquisite can not only be used in aquariums, but also can be used as a car's oil suction pump to siphon diesel from the car.
