Aquael Versamax FZN 2 replacement sponges . These fit inside the filter housing and ensure optimal water filtration. The sponges can harbor millions of bacteria that ensure optimal waste decomposition.

The sponges keep the water crystal clear and ensure that filter maintenance takes little to no time. We recommend replacing the sponges every four weeks. It's best not to replace them all at once, but rather to replace one of the two sponges at a time and rinse the other. For example, with a set of replacement sponges, you can go eight weeks.
