I may be wrong here so anyone feel free to correct any misinformation I may have picked up. I am just repeating what I remember from reading articles and NOT from personal; experience) Therefore - I again suggest you go to any good web site that sells LR (curred and uncured) and read what they say about curing their rock. Uncured rock should have the start of all the good algae (coralline) + wee beasties on them but may also have some decaying stuff that is dying off as well which you wish to let slough off and go through the nitrogen cycle. Meanwhile on that same uncured LR there should be plenty of living tidbits ready to grow. This is why you get the uncured rock + put it in an empty aquarium as it cures. When done you will have the rock slough off any dead junk and have it cycle. The living bacteria in the Rock should be also be blooming and working on the process. In the end you will have fine healthy growth on your now cured rock. You may wish to put some cured LR (from an established tank or buy at least a few lbs. if none available @ home) on top of the uncured to ensure extra healthy coralline algae and bacteria will be speeding up the process. Just to be extra cautious that is. Please - anyone chime in _ I am an armchair expert on this + may be off on some points so feel free to add to or correct any of what I wrote.
