I have it in all my Canister filters, and haven't had any problems. It dose not compact or clog in the filter. It has very good surface area, Overall a great form of Bio filter media. Its not cheap, but you can find it for a pretty good price on the net if you do some searching.
 
good to hear a good review, just filled 2 baskets of my fx5 with it and figured id ask, i'm bad about checking out a product before buying, my lfs had it for $14 a 290g, 10.2oz box, took three of them.
 
I think its awesome my brother has two 2080's with it per superdaves suggestion. Great flow (no compaction) plenty of surface area all in all great media.
