The JUWEL terraces allow you to create varied aquarium floor levels easily and permanently, thereby creating an extraordinary illusion of depth. With their natural brown tones and distinctive rock structure, the Rock terraces are a highly impressive addition to your aquarium. As part of the Rock & Root, decorative range, these terraces go perfectly with the matching colour backgrounds. JUWEL terraces are available in two different formats. The convexly (terrace A) and concavely (terrace B) formats can be combined together in whatever way you wish, offering you creative scope to design your own aquarium. JUWEL terraces are held in place by the aquarium substrate and do not require bonding. This means that you can easily add them to an established aquarium. The Rock terraces are made of several layers of glass fibre-reinforced plastic coated withepoxy resin. This complex production process ensures that the terraces are extremely stable and resistant to surface wear and tear.
