Hop, see you like Schutzhund?!? Not many people are even aware of that this side of the pond, have a Schutzhund 2, Rott, he's getting old now though. You have a Shepard or Dobberman?
Anyways, good article. I think at a high level, there are no shortcuts. Cooking rock helps a lot, especially since most reef tanks have inorganic nutrients higher than the reefs (unless they are polluted). Also GFO, isn't a cure all as mentioned above, the main reason, IMHO, is that it works with mostly orthophosphates (inorganic), whereas the phosphate cycle is different, organic forms of phosphates can become inorganic and vice versa due to bacterial activity upon it....
