*KeyFeatures *Quick & Efficient Water Changes: Our aquarium gravel cleaner utilizes the flow rate valve's connection to the gravel pipe and outlet pipe, allowing water to be pumped out using the vacuum pressure generated by water flow. Dirty water flows directly into the sink or bucket, without the need for electricity or multiple manual pumps. Unlike traditional water changers, it only requires closing the water flow valve to add water, suitable for medium to large aquariums, making cleaning effortless. *Quietly Clean Fish Waste and Gravel: When draining, extend the 12.6 inch gravel pipe into the aquarium. The long pipe allows you to clean the bottom without touching dirty water, making cleaning easy even in tall aquariums. With an internal filter net, fine pores prevent sand from entering; the large diameter of 0.8" / 51 mm helps improve the efficiency of sucking up fish waste and other viscous substances. The entire process is noiseless, ensuring the fish are not disturbed. *Fits Most Faucets: Our connector components come with three sizes of threaded faucet adapters: 3/4 in, 15/16 in, and 55/64 in, which can be used with most bathroom, garden, and kitchen faucets without worrying about compatibility issues. The adapters are made of brass and can withstand water pressure and flow for a long time without being easily damaged. An additional plastic quick connector is provided to avoid problems with mismatched threads or leaking from hard connections. *33 ft Extra-Long Hose: The 33 ft / 10.1 m extra-long PVC hose adapts to the long distance from your living room/room to the faucet, allowing you to completely eliminate heavy water buckets, suitable for small to medium-sized homes. The high-quality PVC is not only durable and flexible but also does not release harmful substances or odors, ensuring the safety and hygiene of the water. *Easy to Assemble and Use: When changing water, after connecting the hose to the water flow component and gravel pipe, first immerse the gravel pipe into the aquarium water and keep its valve closed, then keep the valve of the water flow component open and turn on the faucet, finally open the valve of the gravel pipe, and the dirty water will be sucked into the hose and drained away. ******************************************************************************************************* *Specifications Item Model Number: ASC-100 Hose Length: 33 ft / 10.1 m Connector Material: Brass Connector Adapter Sizes: 3/4", 15/16", 55/64 Faucet Adapter Size: 1.1" x 3.4" / 29 x 87 mm Gravel Tube Length: 12.6 inches / 320 mm Main Material: PVC Product Weight: 2.8 lbs / 1.28 kg, 5% Product Dimensions: 411.7" x 8.7" x 2.3" / 10458 x 220 x 58 mm ******************************************************************************************************* *Pakcage Content 1 x Connector 1 x Three-way Tube Assembly 1 x Outlet Tube Assembly 1 x Seal Tape 1 x Plastic Inlet Nut 1 x Instruction Manual
