1. Put saltwater in tank
2. Put dead sand, if any in tank.
3. Add live sand on top.
4. Let settle.
5. Add live rock.
6. Test for ammonia and nitrite daily.
Ammonia will go up first, nitrite will go up, ammonia will drop to zero, nitrite will later drop to zero
7. Begin testing for nitrate as well. Nitrate should drop to zero as well.
8. When both ammonia and nitrite fall to zero and remain there for a few days, the cycle is complete.
The above assumes that the live rock is uncured or not fully cured (usually a safe assumption) so the die-off will provide the source of ammonia to fuel the cycle.
Good luck.
