Filter Media Other Media

Other than filter foam and biospheres, you can use other media for your pond filtration needs. Lava rock and filter ribbon work similar to Bio-spheres / balls in the sense that it provides a porous surface area for beneficial bacteria to grow on. There are also mesh bags that these types of media can be placed in and put into your filter. The bags make collecting, cleaning and changing out - if needed- a simpler task.
