Florida live Rock has been dealing in live rock for the marine aquarium since 1988 dealing in wholesale and retail of live rock, I have done over 5000 dives in the Gulf collecting. Diving twelve months a year in all different elements water temps ranging from 52 degree to 88 degree. And the visibility being from 3 feet to 8o ft depending on the conditions. Usually with sea,s being 2 to 4 feet for safety factor anything more make it even a more dangerous job at sea . Wholesale of live rock is what I do the most of selling larger volume to wholesalers and retail pet stores in the U.S. Aqua cultured live rock has been a on going bussiness since 1988.
