Cycling a tank

[asylumdown]

If the rock is cured, and sand is 'live', why would waiting show anything? Doesn't there need to be a source of ammonia to see a spike in ammonia? If I were you I'd throw in small shrimp and let it rot. If while it's rotting you see no spike in ammonia, the tank is cycled. If you do get a spike from the waste generated by one little shrimp, it's probably not cycled enough for fish yet.
