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 Crevice Style Backgrounds is using silicone or clips.

FOR NEW AQUARIUMS: We recommend keeping the fish tank dry during installation. Below are two options on how we recommend installing the Crevice Style Background:

Option 1: Using clips - Clip the top of the background first then let the substrate help secure the bottom of the background in place.

Option 2: Using silicone - secure the background first and let the silicone cure before adding any substrate, decorations, water, and fish. 

FOR ESTABLISHED AQUARIUMS: 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 or clips will help secure the middle and top in place. (If using silicone, give time for the 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. **
