Adding Live Rock?????

[mj]

My tank has already cycled. Will adding LR make it cycle again? What is the best way to add LR to an exsisting aquarium? Going to add 45lbs to my 75 gal. Want to be safe rather than sorry........:help:

If the LR you buy is fully cured then you can rinse it and add it to your tank with no additional cycling. If it's not fully cured then you will need to cure it by placing it in a tub of saltwater with a heater and PH. Do a 25% WC every few days and in a week or so it should be cured.

What is the difference between pre-cured and cured exactly?
