Has anyone ever used these?

Like the title say, has anyone ever used these:

Seems like a good idea in theory. Very porous material which enables alot of biological colonization. The 9" x 9" x 4" block seems like it would have quite a bit of inside area for anaerobic denitrification.

 

Thought??.......

Cell Pore has been around for awhile for wet/dry filters but I have never seen it in the large blocks before. I guess you could use it for anaerobic denitrification just like live rock and it probably has more internal areas then live rock. I would use it in a low flow area.

 

Let us know how it works.

If the blocks weren't so freaking expensive, I'd give it a try.

Yeah, for that price you might as well just buy the live rock.
