Sorry to interrupt here. And excuse me as I am "old school". So maybe you can help me understand the live sand/life rock method.
I thought you put in sand, add saltwater, add rocks, and let everything run for a week or so. I then add a mollie and monitor the cycle.
What makes no sense to me is adding sand after the tank is setup and running. Seems to me that would really create a mess.
Perhaps people on this board can clarify my confusion.
