Description
Extremely porous ceramic media for efficient biological filtration. Their surface area and pores are sized to accommodate bacteria necessary for biological balance and to remove toxic ammonia and nitrite.
Hollow design effectively distributes water flow and allows massive colonies of beneficial bacteria to grow on and inside each ring, creating an ideal “bio chemical filter”.
Great for both fresh and saltwater aquariums
Free media bag for easy handling. The zipper-design media bag is reusable.
Size of ceramic ring: 11/16″ x 5/8″. Size of filter media bag: 8 ” x 5.5 “.
