Aqual della Coral consists of 8 basic reefs and many corals of different sizes, shapes and colors. This decoration consists of polyester resin. Combine these reefs and corals to create your own Aqua della reef, suitable for your aquarium. Corals are reproduced as faithfully as possible to nature. Corals of the color of the reef are also offered to people who prefer unwelcome decorations. With their neutral pH, these corals do not detect and can be used in fresh water as in sea water.
