I agree with reefWW96. It is illegal to remove rock/sand/critters from the ocean in Florida unless you have a special permit. Plus, it is bad for the environment. When I lived in florida I picked up some pourous limestone from inland. Soaked it for several days in a bucket of fresh water and placed it in my tank. Now it is covered with all kinds of crystaline, feather dusters etc. Aquaculture is the way to go my friend.
