Our Sustainable Marine Aquarium
Building a Marine Reef
Live rock is calcareous and is covered with algae, bacteria, and marine invertebrates. It is used in marine aquaria to seed them with many helpful organisms which stabilise water chemistry and pH, act as a base for nitrification, and thus function as a biological filter. However, live rock is harvested from the reef, and so is not eco-friendly.
Artificial reef rock is a new, more sustainable, alternative made from a cement-like mixture of calcium carbonate material, shell grit, and sand. It is highly porous, providing a surface on which coralline (purple coloured) and other algae, bacteria, and invertebrates can grow. When used in unison with live rock, it provides a base for reef growth. Its use reduces the environmental and financial costs associated with using large amounts of live rock.
Established artificial rock can then be used to establish new aquarium systems, eliminating the need for live rock.
Did you know? We used 110 kg of artificial rock and only 10 kg of natural live rock to establish our aquarium.
