I have an old Red Sea C-130. There is a block of filter foam in one of the chambers for mechanical filtration. Over time they start falling apart.
I emailed Red Sea the other day to get some more, and they told me that they are discontinued.
I can make them myself, but I don't know where to find the material. I found sheets on Amazon, but they are only 1.5" thick. This block is 4x4x5.
I haven't checked out craft stores. Maybe they would have it, but then I'm worried about leeching.
