What is the proceedure for adding more live rock to a tank that is established and carries inverts and fish? Will putting a new rock in cause another cycle? I'm thinking there must be a way to put the new rock in a holding tank for a while and then transfer it? What are peoples suggestions and experiences with this?
 
Cured or uncured? I've put cured rock into an established tank with no problems. Uncured rock should be cured in a separate tank before adding to avoid causing an ammonia spike.
