Keeping an aquarium with fish or other marine inhabitants can be a relaxing and soothing hobby. Just watching the fish or other marine creatures swim in the tank can calm you down. Many people grow live plants to simulate a natural environment in the fish tank. If you like, you can also apply an aquarium background. It will make your aquarium look aesthetically pleasing and create an illusion of it being bigger than what it is.

An aquarium backdrop does not take up space and you can add it any time you like, without traumatizing the fish. Of course, most people want to know how to apply aquarium background on the outside of the tank. You can apply it on the inside as well but that would mean providing your fish with temporary housing and working on the application of the backdrop after the inside is clean and dry.

Regardless of where you want to apply the backdrop, here are the instructions on how to apply it. This application method teaches you how to apply aquarium background on the outside.

How to Apply Aquarium Background

Things You Will Need:

  • Aquarium
  • Background
  • Extremely sharp scissors or razor
  • Transparent tape
  • Squeegee


Step 1: Measure the Tank Length

Remember, you will be applying the aquarium backdrop on the long rear wall of the tank. After all, it is not called a backdrop or background for nothing! Use a measuring tape to measure the wall length, height, and width. Note down the measurements.

Step 2: Cut the Background

The background that you buy online will have to cut and trimmed to fit on the rear wall of the aquarium. So, once you have the measurement, use a sharp pair of scissors to cut the background so that its size matches the measurements of the aquarium wall.

Step 3: Clean the Outside Wall of the Aquarium

Use a wet, lint-free cloth to clean the outside wall of the aquarium. Do not use any cleaning products as droplets can splash into the water. That would be harmful to the fish.  After cleaning with a wet cloth, dry the outer glass wall with a clean microfiber cloth. Remove things like pumps and hoses out of the way.

Step 4: Mist the Glass

Use a spray bottle to lightly mist the glass. After that, place the background on the misted wall. Be careful to align the edges of the backdrop with the edges of the glass.

Step 5: Fix the Aquarium Background

After the background is properly aligned with the aquarium wall fix it in place using transparent tape. Apply the tape on the top portion to keep the backdrop in place. In case the background is static-cling type, you will not need the tape. Remember to peel away the opaque backing before you position the backdrop on the wall.

Step 6: Remove Air Bubbles

After putting the tape on top to set the aquarium background, mist it gently with some water. Run a squeegee on the background from top to bottom. This will remove air bubbles. Always start from the center and work to the outer edges. Once this is done, stick transparent tape at the bottom and sides. Voila! You are done.

The Bottom Line

Now you know how to apply aquarium background. It is a simple and quick way to beautify your aquarium. Go ahead and give it a try. You will love the look and feel aquarium backdrops create.
