Marco Rocks Hybrid Rock per kg

This form of Marco Rock is exactly the same as the types that you are familiar with except it’s a different shape. It’s not quite shelf, not quite Reef Saver, but it is quite unique! It is recommended that you first use Foundation Rock on the aquarium base and add Hybrid Rock to create some height and support before adding some Premium Shelf Rock to finish off your stunning display. Excellent for creating caves too. It is recommended that these rocks are stacked carefully and cemented together at key junctions with E-Marco-400 mortar. Sold per kg.
