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!! Back to Nature Slimline backgrounds are approx. 10 mm thick and come in two colours White Limestone and Red Rock. Slimline backgrounds are available in several sizes that interlock this means they can be installed easily and quickly in nearly any tank.
