How to Install ColorCast Frosted Background Film

Follow the steps below to install your background film. If you don't have access to the back of your aquarium, you can simply cut it to size and tape it with clear tape. As long as you stretch it well while taping it, will be good until the next time you have access to the back of your tank to install it properly.
Our films don't have any glue or adhesive, it sticks to your glass with static cling, when you remove it, it will not leave any residue.


Remove any accessories such as filters and clean your back glass.

Step 1

Measure your aquarium back glass dimensions. (Do not include the frame if you have one)

Step 2

Cut your background film a couple of inches more than what you have measured. ( You will trim it to size later.)

Step 3

Thoroughly wet the back glass by either spraying clean water or wiping it with a soaking sponge/cloth. Having more water on the surface makes the installation much easier and bubble-free. Make sure you put a rag under to catch dripping water so it does not damage your furniture/ aquarium stand.

Step 4

Peel off the protective film. The smooth side of the frosted film is the side to cling to the glass.

Step 5

Place the film on your glass. First, align the straightest (factory cut) long corner with the top of the glass and later the straightest short corner with one of the sides. Now you should have little excess on the bottom (lower horizontal edge) of the glass and on one of the vertical sides.

Step 6

Squeeze out all the water and air bubbles with a smooth and straight object such as a credit card. Don't apply too much pressure as it may scratch or rip your background film.

Step 7

Trim- off the excess background film. You should be trimming off only two sides if you aligned factory-cut straight corners properly. The bottom part will be covered by gravel so don't worry if it is not 100% straight. For the vertical side, easiest and safest way is to hold the razor 45 degrees to the edge of your tank and rest the side of your razor on the edge of your aquarium as you go cut down. Be extra careful not to cut the silicone of your aquarium. This may cause your aquarium to burst.

Step 8

Background film is now installed. Install your background light brackets. We recommend attaching the mounting brackets to your stand with the included wood screws. However, if you have a framed aquarium, you can also use the included suction cups.
