These biomedia balls can be used loose or in the mesh bag with plastic zipper.
  • Over time, porous lava rock becomes clogged with debris decreasing its surface area so that its ability to house and grow good beneficial bacteria plummets. Our bio balls’ uniquely spaced spines allow most debris to pass right through them. Lava rock has tiny pores which make it difficult to clean while bio balls in most applications never need cleaning..
