PhosBan Reactor Foam Disks
Two Little Fishies PhosBan Reactor Foam Disks are 2-pack replacement sponges that sit above and below the filter media inside PhosBan reactors (models 150 and 550). They hold the media bed in place and prevent fine granules from escaping into the aquarium, for use in freshwater or saltwater systems.
