White, porous rock ideal for reef aquariums.

MarcoRocks was founded in 2006. Spawned out of the belief that our industry needed a responsible "green" alternative to wild collected live rock. They quickly out grew their Mass Location
In 2008 they expanded into a Key Largo location and thanks to your overwhelming support we quickly out grew that location also.

In 2010 they moved to our current location in Homestead Florida, A fully licensed Florida aquaculture facility on over 5 acres. Now exporting to 7 countries, they produce all of our own rock products and are the largest producer and shipper of aquarium rock in the USA.

Preparation, rinse in clean water before use.
