It's a great article, but it is based upon the supposition that you placed your newly purchased live rock in the tank at the time it was innitially setup. My comments referred to my rock cycling in a second tank for 3 months prior to setup. The result was hardly a cycle at all. Ammonia stayed at undetectable levels, Nitrite was barely detectable, and Nitrates never climbed above 3.5. (They fell to zero on the 10th day). Even so, I did not add anything other than snails and a detrivoire kit to the tank until 8 weeks after nitrates read zero. I think this gave me essentially a 3 month head start. The detrivoire kits are a big help to a sandbed as well. Eric has recommended them in past articles, and Ron Schimik suggests buying two of them from separate sources for increased bio-diversity.
The signal I used for adding corals was when coralline shows up on the glass. I read that somewhere years ago, and I think it's a good one. As far as adding the anemone at the one year mark, I would still disagree. (If done so with care). ie excellent water quality, and a light bioload.
The bacterial life in the sandbed is obviously very important, but it is far more important to people who tend to add alot of fish. They are the real source waste and deteriorating water quality. Especially herbivors like tangs. They are large, eat lots of food, and expell 94% of what they take in. Anemones don't produce that kind of waste. I feed mine 1 silverside every 5 days.
My livestock consists of 2 true percs, 1 Royal Gramma, and a Flame Angel. A very light bioload for a 75G. Excellent water quality and the right lighting are the keys in my opinion, and both can be achieved in under a year.
