ROCKY STYLE

Our most popular and thinnest style background sold!

Universal Rocks
ROCKY STYLE AQUARIUM BACKGROUNDS

Available in as many as 21 standard sizes, as well as custom sizes at your request. This mold was originally taken from a basalt rock formation approximately two hours south of Sydney, Australia. Although very thin, our Rocky style backgrounds still have a distinctive rock finish, making them a perfectly non-obstructive rock background for any fish tank aquarium. They take up no more than a quarter inch of your tank, and are also one of our most cost effective and easy to install options.

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 Rocky 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 Rocky 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. **

IMPORTANT

All Rocky Backgrounds arrive half an inch shorter than what is shown, to ensure a perfect fit and are ONLY available in brown EXCEPT for custom backgrounds.
