Aquarium Background Blue 120x45cm

This large-format dual-sided background film for 120cm tanks prints deep blue on one face and matte black on the reverse, giving hobbyists two distinct background options without buying separate films. The film is supplied on a roll at 120x45cm and applies to the exterior of the rear glass panel with the chosen colour facing inward toward the tank. The adhesive is applied to the blue side only, so the blue face bonds to the glass while the black side faces outward when using the black option — simply apply the film with the desired colour facing the tank interior. UV-stable inks on both faces ensure long-term colour retention under aquarium lighting. Trim as needed with scissors to match non-standard tank heights.
