Marco Rocks Premium Shelf lends itself to that perfect shelf scape that is reminiscent of a multi-tiered reef scene. We recommend stacking the rocks horizontally over the MR ReefSaver Foundation rocks.
Marco ReefSaver is a natural calcium carbonate rock that is harvested on land from an ancient reef system buried when the Florida land mass was formed. It is not harvested from a marine environment it has no negative impact on our delicate reef or marine ecosystem. A unique chemical-free cleaning process produces great looking rock that's totally pest free and environmentally friendly.
It is highly porous and beautifully shaped. If you're lucky, you might spot ancient fossilized corals in the rocks.
MarcoRocks is the choice of many public aquariums, aquaculture facilities and custom tank builders all over the world.
Sold by the pound. Pieces range in size from 8" to 16" across, and 1" to 3" thick.
Please include notes in your order if you have any size preferences and we will do our best to accommodate you. We will contact you if we won't be able to come close to your request. It helps to let us know the size of the tank the rock is for as well.
