This will be your foundational rock to use for constructing your custom reef.

An 18 kg mixed box contains stones ranging in size from 10 to 30 cm, although most pieces are typically 12 to 16 cm in size. Due to the natural origin of the material, harvested from the remnants of an ancient reef on land, the shapes will be random and heavily structured.

DD Marco Coralline Rock is a completely natural calcium carbonate rock, now supplied in colored form. A new, specially developed, lacquer-free process is used to simulate coral-covered live rock. The purple coral color instantly gives your new reef structure a natural and established appearance, while over time, real coral algae will populate the surface.

Sustainable

The natural rock is sustainably harvested from the remains of ancient coral reefs on land that rose from the sea millennia ago, forming part of Florida, the Keys, and the Caribbean's structure. Since the rock does not come from a living marine environment, it has no negative impact on the world's sensitive reef or marine ecosystems. Being a completely natural reef rock, it has the perfect porosity for the colonization of beneficial bacteria to create a thriving ecosystem in your aquarium.

Shaped by nature

Each stone is entirely unique and ideal for creating beautifully realistic marine environments. In many stones, you can even see the pronounced coral structures of the ancient animals that created them. This not only makes this product environmentally friendly for living coral reefs but also provides the additional benefit of using dry natural rock, which is entirely free from pests and hitchhikers, ensuring no unwanted organisms enter your aquascape.

Buffering

The calcium carbonate composition of the rock provides a natural buffering capacity in the aquarium without any negative impact on pH. No additional curing is required.
