Best unique shaped stone, combination of discs and normal Marco Rock.

This Hybrid MarcoRock seems to do it all. It's quite easy to use and forgiving. The silt structure allows for spacious ledges and overhangs, which is truly the look of great aquascapes. The Reef Saver component provides the mass, height, and robustness characteristic of classic live rock. We recommend using Hybrid Rock over MR Foundation Rock. To connect Hybrid Rock structures for more dramatic caves and ledges, consider adding a few pieces of MR Shelf Rock to the mix. It can be bonded with E Marco-400 for permanent installation.

Our MarcoRocks are the finest all-natural aquarium rocks currently available for the aquarium enthusiast. They are a once-living, natural reef rock.

Completely natural calcium carbonate stone. No chemicals or additives. You can often find fossilized ancient corals in the stones.
