INSTALLATION

**ALWAYS USE INTERIOR DIMENSIONS WHEN MEASURING FOR THESE PRODUCTS**Rinse the background with a hose or power washer to get rid of excess coloring before placing it into the fish tank (please keep in mind that there will always be some color residue, though it is not harmful). The best way to install Universal Rocks backgrounds is using silicone.

We recommend keeping the fish tank dry - securing the background first and letting the silicone cure before adding any substrate, decorations, water, and fish.  We recommend draining the aquarium at least half way. For a tight fit, carefully create a trench by moving the substrate out of the way, giving just enough room for the background. This way the gravel will help secure the bottom of the background in place while the silicone will help secure the middle and top in place. Give time for silicone to cure before refilling the aquarium. **For established aquariums (6 months +) we suggest doing a gravel vacuum water change one day prior to installing your Universal Rocks background. If maintenance has been consistent we see no concern with installing right away. **
