Bio-Sphere media caddy

A tower, cage or cradle for Maxspect Bio-Spheres (or Bio-Cubelets), sized to your sump.

Holds filter media spheres apart so water flows round every one, in a stack of layers, a cage basket with a handle, or a low open cradle.

You set how many spheres it holds and the space it must fit in your sump or AIO chamber; no post is taller than one sphere, so nothing tall and skinny can snap.

What you can change

  • Style: rod tower, cage basket or open cradle
  • How many spheres, or a grid you choose
  • The sump space it must fit
  • Handle, feet and flow openings
