Prep: 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.
Step 4: Peel off the protective film. The smooth side of the frosted film is the side to cling on the glass.
Step 5: Place the film on your glass. First, align the straightest( factory cut) long corner with the bottom of the glass and later the straightest short corner with one of the sides. Now you should have little excess on top of the glass and on one of the sides.
Step 7: Squeeze out all the water and air bubbles with a smooth and straight object such as a credit card.
Step 8: Trim- off the excess background film.
Step 9: 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 framed aquarium, you can also use the included suction cups.
