Keep your media or calcium reactor operating at peak performance with this replacement open-cell foam sponge. Measuring 6¼" outside diameter × 1¼" thick, this sponge helps contain filter media while allowing consistent water flow through the reactor.
The durable 20 PPI open-cell foam is suitable for many media and calcium reactors that use a sponge of similar dimensions. The finer pore structure helps retain disintegrating aragonite media while maintaining consistent water flow, making it especially well suited for calcium reactor applications. It may also be useful in other filtration applications, including pond and aquarium prefilters.
Please verify dimensions before ordering, as compatibility varies by manufacturer and model.
