Ziss Zet-65 replacement sponge.
The Ziss ZET replacement sponge acts as a filter for the egg tumbler. Because the sponge is located between the aquarium water and the egg tumbler, a small suction force is created on the sponge. This way no dirt is sucked into the egg tumbler and the eggs remain clean.
