Starting a new reef aquarium, I have 120 pounds of Live Sand for a DSB and so far 45 pounds of Base Rock. I am planning on buying a couple of large pieces of Live Rock from PETCO. They carry live Fiji rock and they sell a 5-6 pound chunk of this for 20.00. I plan on getting around 2 chunks of this to seed my base rock for a total of 56-60 pounds of rock in my 46 Bow. Has anyone bought live rock from PETCO? Their LR looks good, and has alot of coraline on it allready. Tell me your thoughts.
