Linked on page one of our cycle thread under types of cycle descriptions #1, well done. Darn good info thread + follow up
Can you post just a semi close-up pic of your live rock spotty coralline we gotta tie in a visual
Barry's mention of curing live rock in a nano is worth detailing, we have a section for it in our thread because that kind of live rock has visual cues just the same which allow us to verify it, and utilize it, without testing (anticipating that die off he mentioned)
The die off overwhelms inherent bac; cleaning most of it off before you use the rock in tank to continue curing is one way to speed up/allowing it to cure and wait is another/not buying that kind but rather simple coralline live rock is another cuz it's always ready
The visual cues for uncured ocean rock are that it's so nice, nobody else's live rock on the whole board looks like it

so be skeptical of it being ammonia free.
It will have a diversity/coloration/salad-like plant growth all around, possibly tunicates and sponges, free corals etc you can't find this rock after a few years on average Joe or Jane's reef tank thread here or anywhere, because aquariums typically select down to coralline and the usual visual attachments we're used to given time.
We show pictures of that type of rock vs common live rock, nothing fancy, to show these are two different classes of live rock with fully predictable ammonia profiles.
Dry rock
Vs uncured ocean rock
Vs the ever-trustworthy, drain tolerating, smells normal at the lfs, nothing dead and rotting cloudy in the vat the rock sets in for display, relocating from LFS to home is a breeze common live rock
