Unchain your creativity and create your unique, individually designed 3D rock background with Back to Nature rock modules. Rock modules can be combined as well with 3D backgrounds and Slimline backgrounds.
The rock modules are arranged for a coarse design without gluing in the aquarium. Test which combination works best. Overhanging rocks create depth. Fix the rocks with wooden strips and filter foam.
Glue in the the rock modules and adjusted if necessary. The easiest way to cut rocks is with a jigsaw. Afterwards, the glue joints are pressed off with sand. Wait for 12 − 24 hours until the silicon has cured. Then you can start up the aquarium. Enjoy yourself-designed Back to Nature rock biotope!
