I am about to add some live rock to my 125 gallon. At the moment I have 100 lbs of base rock in my tank. I plan on buying 45 lbs of fiji live rock to seed the base rock. I am in no hurry for live stock but I was wondering about how long it would take for the live rock to grow to the base rock and are there any precautions when I add the live rock such as handling it when I put it in the tank or dye off. I will cycle with cocktail shrimp. Any other suggestions I would greatly appreciate. Thanks
