LANDEN Filter Hose Tubing is used to connect canister filters and lily pipes in aquarium filtration systems. Available in two standard sizes, it is compatible with all types of canister filters. Smooth interior and exterior walls for easy media flow and cleaning inside. Comes with slight tints to hide organic matter, fish excrement and other deposits that may adhere to the hose after a long time. This keeps the hose tubing visually clean. Made of high quality PVC, environmentally friendly and odorless, friendly to aquatic life. The tube wall is thick, light in quality but with good flexibility, and can be bent at will but without creases. Suitable for freshwater and saltwater aquariums.
