Unless your biomedia is literally disintegrating, there is no need to replace it.

Switching your biomedia may have some effect on your flow rate (i.e. if it is "looser" then the water will flow by more easily) but it will probably not make a perceptible difference.

In any case, your biomedia will clog over time, requiring cleaning anyway.

I use the bio media (biomax) that came with my fluval canisters as well as broken up pumice. I am apparently cheap though(always looking for a non-brand replacement).

The Seachem matrix appears to have a very large surface area in comparison with most other media options I have looked at. It's pricey though.

For the princely sum of $1-$4 you can get yourself some of that ancient pumice from a garden center or agregate supplier locally and see if you like it.:smile: Rinse it first like anything else.

As far as replacement goes, like previously mentioned, unless it is disintegrating should not need replacing. It does get gooped up after a while (three months +/-) though so a quick rinse with dechlorinated water will restore it well enough to keep proper flow.

For the sake of clarity - you never want to "clean" your bio media. That will cause an ammonia spike and possibly kill your aquatic friends. <-- No argument intended Darkblade48.
