D ) NOW you are "Cycling"...
Ammonia levels go up...peak...and then go down as bacteria convert Ammonia to NitrIte...
As Ammonia level goes down you will see NitrIte level rise...peak... and then go down as bacteria convert NitrIte to NitrAte...
NitrAte level will start to rise as Ammonia and NitrIte levels go to 0
At this point (Am 0,NitrIte 0, NitrAte 10+) you can do a water change to "refresh" the tank and add your first fish...
There really isn't much you can do to "lower" Ammonia/NitrIte levels other than water changes to "Dilute" Doing so will only prolong the cycling proces...The tank must go through this cycle to establish proper levels of bacteria...
As long as there are no fish in there it would be best to just let it go through its "natural" cycle...
As far as life on the rock...some (most) will make it some will not...The "natural" die off is probably what started your cycle in the first place...
