I use a 14 gallon Rubbermaid container with a powerhead, saltwater, and a heater. This will do a 45 pound box of live rock. Usually takes about 3 weeks. In the mean time I do 3 or 4 100% water changes and turn on only actinic fluorescents for a couple hours a day. You have to be careful not to put to much light on the rock or you will have an algae bloom. I test for ammonia before doing the water changes and remove unwanted sponges and other junk when it shows up. It may be smart to wear gloves to handle it for the first time out of the box. I am sure others have good ways to do it and will share. Did I forget anything?
