MarcoRocks was founded in 2006. Spawned out of the belief that our industry needed a responsible "green" alternative to wild-collected live rock. Outgrowing their northern location, in 2008 they expanded into a Key Largo location and thanks to your overwhelming support we quickly outgrew that location also. In 2010 Marco Rocks moved to their current location in Homestead Florida, A fully licensed Florida aquaculture facility on over 5 acres. Now exporting to 7 countries, they produce all of their own rock products and are the largest producer and shipper of aquarium rock in the USA.
