well as you know I had 200 lbs. waiting for the tank to be finished and there was essentially no cycle when I put that in the tank but I had a huge diatom event. I set the new rock on top of that old rock and I am having considerable die-off of the macro-algae, while new buds are developing within the last day.
One key issue is that I am doing this cycle without a skimmer so that tends to create a more pronounced but faster cycle. I can't expect to be through the ammonia part of it quite yet, but it will be soon.
