D-D Marco Coralline Rock is a totally natural calcium carbonate rock supplied using a proprietary paint-free process developed to simulate coralline-covered live rock. The coralline finish allows your new reef structure to look natural and established immediately, whilst waiting for the surface to be colonised by real coralline algae.

The natural rock is sustainably harvested from the on-land remains of ancient coral reefs which millennia ago rose from the ocean to form part of the structure of Florida, the Keys, and the Caribbean. As the rock is not taken from a living marine environment, it has no negative impact on delicate reef or marine ecosystems, and being a completely natural reef rock, has the perfect porosity for colonisation of beneficial bacteria to provide a thriving ecosystem in your own aquarium.

Each piece is totally unique and ideal for creating beautifully realistic marine environments. In many rocks you can even see the distinct coral structures from the ancient animals that created it. As well as making this product environmentally friendly to living coral reefs, the added benefit of using a dry natural rock is that it is completely free from pests and hitchhikers, giving you peace of mind that unwanted organisms are not introduced with your aquascape.

The calcium carbonate composition of the rock will provide natural buffering capacity in the aquarium without negative effects on the pH. No additional curing is needed.

By using either the Aquascape Mortar Bonding Kit or D-D Aquascape Construction Epoxy it is possible to build elaborate, permanent structures by bonding the rocks together.
