The Spring Filter is a cylindrical component with a grooved wall designed for use in aquariums and tanks, where it serves as a filter element or as a housing for filter material. The outer surface has a series of regular vertical grooves, while the hollow interior is crossed by a helical spring that promotes the passage and distribution of water. Its compact, self-supporting shape makes it suitable for insertion into existing filtration systems or as a decorative and functional element inside the tank. It measures 20 cm in height
