In most aquariums around the world, film is used as the most affordable and affordable accessory as a background. In pet stores there is a huge selection of films with different patterns and from different materials.
Background films are different in that they are internal and external. Consider the advantages and disadvantages of one and the other.
The films are distinguished by their simplicity of installation (they are fixed with the help of ordinary scotch tape, the film is pressed tightly and straightened) and a relatively low price, due to which they have gained high popularity. The most common are external films: because of the ease of installation, they can be replaced quite often without disturbing the inhabitants of the aquarium.
Service life is very long.
Internal background films are less popular, but they look more aesthetically pleasing and more beautiful. They are attached to the back wall of the aquarium from the inside on the sealant (for example silicone). The downside is a higher cost and low life (it is recommended to replace the background every 2 years)
