Ocean Free Sponge Filter Bio Foam Filtration for Aquarium and Fish Ponds

Ocean Free Sponge Filter Bio Foam Filtration for Aquarium and Fish Ponds

Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is air pump and airline tubing, and you've got a filter that is fully contained within your aquarium. Sponge filters are completely reusable, don't need any replacement cartridges, and last for several years. Plus, they are gentle enough for betta fish, baby fry, shrimp, and other slow-moving species. Trusted by fish farms and wholesalers, they are an excellent choice for aquarium filtration that you can set and forget.

The Ocean Free sponge filter is designed using quality foam so that it can go many weeks between cleanings. The weighted base will immediately sink to the bottom of your aquarium, so no more floating up after a water change or initial installation.
