I have been following that thread on RC for quite a while now and have been using the pellets for a few weeks. For over 2 years I have been dosing vodka and zeo products, and my nitrates and phosphates are presently fine, but I remembered what Eric Bornman said at the BRASS conference about carbon dosing adversly affecting bacteria populations on corals. This product eliminates that concern because the bacteria grow on the pellets, not in your display, corals, etc. So I have been slowly reducing the vodka and hope to not dose at all in the near future. Also if you shake the pellets up daily like you would zeolites, the mulm that comes off them is incredible and the corals feed off it. I'm hoping this aspect might help me in my quest to keeps some NPS corals. I have a strong feeling that this is going to be the next big thing in reefkeeping.
