Liaflor is germ-free as well as chemically and biologically neutral. Liaflor drains and can be reused. It is eco-friendly produced and its disposal does not pollute the environment.
Unlike cheap inferior quality clay, Liaflor German expanded clay will not break down over time. Cheap quality expanded clay equates to false economy as it breaks down, becomes muddy and will block up your pumps!
