What are polyester backgrounds?

[Thomas]

I'm doing a search for aquarium backgrounds and I keep seeing this 'polyester' background type on Amazon. Has anyone used them before and would like to share?

I don’t know much on the topic, but polyester is a plastic, so it can be molded into any basic shape.

I used to use them a bunch. And my father still uses them. They're basically a plastic sheet with a design on it that you stick onto the back of the aquarium using water and/ or tape. Depending if you want it attached right or not. When I planned my 40g tank, I was originally going to use a solid black background but decided against it because it caused reflections. They're really about personal preference in appearance, I personally feel like they're a bit over the top in design but then again I like my white wall being the background.

I don’t do background on most of mine but ones in front of windows I do. I like this to attach it works well

This a polyesters background , it’s applied like window tinting, soapy water squeegeed out from center to sides. Could just tape it on like other backgrounds. I applied this one after it was set up. Do yourself a favor if you decide to go this route do it pulled away from the wall 😬😬😬. Not the best application, if you zoom in you can see the black dots . Wash your glass really well.

all in all I would recommend them. Pros; Don’t have to worry about them falling down, no water getting behind, seem to have a wider range of options, and smooth look if applied correctly. Cons; little more expensive, harder to apply ( even if not pushed up against a wall), can be moved but not easy,

This little kit gets the black dot bubbles out 😉
