This product is the excess media from our sponge filter manufacturing process. It consists of small cylinders and cubes. We sell it below cost, which is a great deal for those who can use it. It's ideal for placing in canister filters, outside power filter boxes, box filters, and bio towers. It is very porous with tons of surface area, creating an idea media for culturing beneficial nitrifying bacteria. Each package contains a minimum of 230 cubic inches of Reticulated Foam Bio Media (this amount fills a 1 gallon jar). We sell this at below cost.
It doesn't take a very large range of media types to cover most filtration possibilities. These, along with our Custom Foam pieces cover most of what anyone will need.
