I have a fairly large biopellet reactor from reef dynamics (used to be Euro Reef). I used it on a 220gal tank, I'll sell it for $150. If anyone knows the guy that made these and the old Euro Reef Skimmers, you know the high build quality. I decided to not use bio pellets anymore.It looks like this one. This is not a picture of mine. $150
