I am new to having a saltwater aquarium i have had my tank for about two weeks and just want to make sure im doing this right. I bought about 30 pounds of live rock from a local guy and i put it in my tank hoping to start my cycle but it hasnt happend yet. someone told me that if i bought cured live rock that it wont cycle and i could start adding fish and coral. Is this right or should i buy something to start my cycle??
