ELEBOX Aquarium Background Blue Black Fish Tank Background Picture 2 Sides Fish Backdrop for Aquarium Wallpaper 24" x 71"

Perfect for my new 40g tank. I love the way the scape looks with the black background.

It is made of good material and fits the tank well, but beware it DOES NOT ADHERE OR STICK TO THE TANK. I had to use tape for mine. Its basically just a black and blue sheet.

This product is NOT self adhesive. However, if you mix 1 cup Vinegar with 1 Cup water to spray on the glass it will stick perfect.To apply: Mix the Vinegar and Water into a spray bottle. Liberally spray the glass of the tank and lay it on the wet surface. Use a squeegee to smooth down and remove excess water and air. Once dry, it's stuck.Need to remove is, grab a corner and pull it off.

I put the black side up on the back of my new 55 gallon and it actually look like a mirror! Too glossy for my taste, so I will be sending it back

Looks nice on my 55 g

Wonderful in large fish tank

Like most people have stated, it does not have adhesive.But, you can still apply it I'm the same process as vinyl and/or window tint. I used a 1:1 vinegar and water solution. Sprayed the background, placed/adjusted it to where I needed it. Then I used my squeegee to get all of the bubbles/liquid out. It is now adhered to my glass w/o any type of adhesion/glue/etc. I simply taped the edges to reduce water getting through.Looking at it, you won't even be able to tell it doesn't have some type of adhesion.

This is a 40b. Looks great. Will update photos once I get it planted and filled with water. Please ignore the scratch on the glass.I have never installed one of these before. It is a little tricky on the ends if you don’t cut it right but other than that it went on super smoothly with soapy water. It isn’t a sticker you stick on the back of your tank and it’s not attracted to the glass like some people in the reviews think. You clean the glass,apply soapy water, place the film and squeeze out the bubbles and water, trim the edges and done. There are no instructions in the packaging but they are on the Amazon product images and description.

I got this for my 55 Gallon. It fits perfectly and the blue came out like an indigo blue, my fish really stand out now against it.

It sticks to the glass very good
