Hi I have tetra pond bio filter and want to know if there is anything
better then the filter material out there to use their filters are so
expensive here over twenty dollars I also use the tetra uv light so have no
problems with green water but need something good for filtering out the
small things in the water any suggestions?


You can get porous high density material at Lowes, or any hardware store. The
only recommendation I can make on the small particles is to clean your filter
more often. But you are always going to have some suspended particles, even if
the water appears transparent.
