The aquacultured
LR from liverock.com is NOT CURED! Their rock is harvested & placed in holding tanks.
In my 2 experiences, you will not cycle but will have a small
NH3 &
NO2 spike for a day or two if placed in a well established tank. In my other scenerio, if placed in a new tank, then you will go through a full cycle but at a much shorter timeframe than a traditional cycle. (about 2 weeks)
