I want to start a saltwater tank, but I have a few questions on cyling. Ive had FW tanks for a year. My understanding is that if I drop in cured live rock(30lbs), the bacteria on that will be enough, and its instantly cycled, is this true. I have a 30 gallon tank that will be FOWLR. I plan to get a clown fish, then a scooter blenny about a week after I put the live rock in, is this all correct?
