cycling with live fisg also burns their gills. you can do a small water change before you get the new rock then I would weight till after the 1 month mark. For a tank to fully cycle it can take upto 6 months to establish a tank completly. useing cured live rock will speed up the cycle but not much a 4 week cycle time maybe sped up to a 3 week cycle time.
Have to run and pick up me daughter but I will keep an eye on this thread.
