2-in-1 multifunctional cleaner: The gravel cleaner is very suitable for water changing and sand washing. The large diameter suction pump has a built-in round hole filter to prevent small fish and grit from being sucked in. Effectively removes feces and food from the bathtub, and the residue is separated to ensure the freshness of the water. High-quality material: This aquarium water dispenser is made of high-quality plastic and can be used for a long time. Soft and transparent PVC pipes can transfer liquid faster. All materials are individually provided, can be disassembled individually and are easy to clean. At the same time, disassembly and assembly are simple and easy to carry out. Simple operation: The siphon pump is easy to grasp. Just press the pump a few times and the water will flow out automatically. High-quality PVC pipes will not collapse and therefore block the flow of water. (Note: The position of the water outlet should be lower than the position of the water inlet.)
