Back to Nature Aquarium Backgrounds are an amazing addition to your aquarium and really make you feel you have a real piece of nature in your home!! Their unique look is the result of large scale tests of both different methods of production and a variety of materials in order to find the optimal durable product for tough aquatic environments. The materials used in the Back to Nature backgrounds include polyurethane the mixture of polyurethane used has been carefully tested for many years and does not release any chemical substances into the water which may be harmful to fish plants and other living organisms nor does it affect the chemical composition of the water. For this reason Back to Nature backgrounds may be used in all kinds of aquariums even marine aquariums. Back to Nature backgrounds are produced using a unique colouration process which prevents the colour from ever flaking off. The colour is combined with the material of the background itself in a chemical reaction. As a result the surface layer will remain intact even after years of wear and cleaning. Back to Nature backgrounds are designed in a way that leaves sufficient space behind the background so that it is possible to hide all the technical equipment and also as many people do use the whole space as an enormous biological filter chamber that is effective for years without cleaning. The Rocky Juwel is a "flatter" background which fits perfectly into modern aquarium furniture which is not as deep (for example Juwel). In spite of these backgrounds' relative flatness and their reduced need for space in the aquarium there is still enough space in one corner for both the filter and the heater. This background is supplied in two sections simplifying installation. Rocky Juwel should be installed in aquariums with a minimum depth of 25 cm (30-40 cm or more is preferable). Dimensions 100cm x 47cm
