So I ordered a canister filter (Sunsun brand) and it is my understanding that it does not come with much media. I am short on money so I don't have much of a filter media budget. I do have some ceramic rings but not enough.
I have had these building block type things for many many years now and recently I have been wondering if they have the potential to be used as bio-media.
The building blocks are made entirely out of plastic.
The building blocks are covered in little (for lack of a better word) "rods" that stick out from the main blocks (this is what allows them to stick together for building), similar to the "rods" that stick out from a Coralife bio-ball. Each "rod" sticks out a little over half a centimeter. The "rods" are about 3 millimeters apart.
But enough descriptions here are some pics (click on the image to see more detail):



I have different shape variations of the building blocks as well.
So would this work as bio-media in addition to my ceramic rings in the canister filter I am getting?
