Bio blocks- long shot

[fish_freak]

Ok I know this will be a long shot but a couple of years ago I bought these bio blocks for my Aqua Clear 500's from that fish place. They are big blocks of bio meadia shaped to fit snugly on top of the foam pad. I was wondering if anyone knows who manufactured these and where I might be able to get a hold of some more as I broke one yesterday and that fish place no longer sells them.
thanks

they are cell pore. it might be hard to find because i dont think they are made anymore, big als had a close out on them before. i dont like them because they do break. just get the normal 1 inch cell pore cubes and put them in a media bag.

Thanks that is what they where called. If I cant find them then I will go with the media bag but I like them. Mine are 2 years old and I imgaine I wont be able to find them but thanks for replying I didnt think anyone would know what I was talking about.
