Filter: Cube Filter Foam

All pieces are 29" long (30 ppi). 

Made from our Pro-Level Reticulated Foam, specifically suited for colonizing nitrifying bacteria at the highest levels in your aquarium.

Our aquarium filter foam is waterproof and is made without any fire retardants, mildewcides or any other harmful chemicals. It is 100% fish-safe. It is also the most durable, highest surface area foam that you can get. We have been personally using this exact foam in our professional hatcheries for 35 years. In fact, some of our original filters are still in use! As an added benefit, it is made right here, in the U.S.

We will custom-cut the length or width of any piece to the size you want and send any left over cut-offs along with the order. Shipping: These will be rolled, folded or squeezed to a smaller size to avoid extreme dimensional weight charges by the carrier. They will rebound to their original shape after a day or so of being unpacked. Please Do NOT order by any Next Day, 2nd Day or 3-day services. The overcharge dimensional weight is not accurate in the shopping cart and you will owe more money to ship by those methods. Priority and Standard are the only options that the cart will be correct on.
