Use a two-sided Superfish Deco Poster D to conceal cables and equipment behind your tank. Follow these steps for measuring, cutting, and mounting without bubbles or tape failure.
Quick answer
Measure your tank’s back glass, cut the Superfish Deco Poster D to size, choose the side you prefer, and fix it to the outside rear glass with tape or a gel—never inside the tank. This hides cables and equipment while letting you change the look by flipping the poster.
Why the rear glass is the right place for cable concealment
Cables and tubing usually run down the outside back of the tank, so a poster fixed to the exterior rear glass hides them without taking up swimming space. Avoid attaching anything inside the aquarium, where moisture and fish can damage it.
Because the Superfish Deco Poster D is not self-adhesive, you can remove and reposition it without scraping glue off the glass. That makes it a practical choice if you rearrange equipment or move the tank.
When tape alone may not hold
Tape works on clean, dry glass, but humidity or an uneven rim can weaken the bond over time. If the poster starts to peel, switch to a gel fixative or add tape along more edges. The poster’s two-sided design means you can flip it later without buying a new background, but plan the fixing method so removal stays easy.
Step-by-step: fit and hide cables with a Superfish Deco Poster D
- Measure the rear glass: Use a tape measure to record the height and width of the outside rear glass, not the tank’s outer frame. Common mistake: measuring the frame and cutting the poster too small. Write the measurements down and double-check them before cutting.
- Choose the poster size: Pick the Superfish Deco Poster D size closest to your measurements: 60 x 30 cm, 60 x 49 cm, 100 x 49 cm, 120 x 49 cm, 120 x 61 cm, or 150 x 61 cm. If your tank falls between sizes, choose the larger one and trim it down. A larger poster gives you margin for trimming; a smaller one leaves gaps.
- Cut to size: Lay the poster flat and cut with scissors or a blade along a straight edge. Check the fit against the tank before removing any more material. Common mistake: cutting in one pass without test-fitting, which can leave the poster short on one side. Cut slightly larger than needed, then trim in small increments.
- Select the side to display: The poster is two-sided, so decide which image faces out before mounting. Dry-fit both sides against the tank to see which looks better with your room lighting and decor. Flip the poster before fixing it—once taped, changing sides means removing it.
- Clean the glass: Wipe the outside rear glass with a lint-free cloth and let it dry completely. Tape and gel adhere poorly to dust or moisture. Common mistake: skipping this step and finding the poster peels within days. Clean glass is the foundation for a secure hold.
- Fix the poster to the outside glass: Use tape along the top edge first, then smooth the poster down and tape the sides and bottom. If tape alone doesn’t hold, apply small dots of aquarium-safe gel at the corners. Never use adhesive inside the tank. Start at the top and work down to avoid trapping air.
- Route cables behind the poster: With the poster fixed at the top, tuck cables and tubing behind it before sealing the side edges. Keep power cables away from any water source and use drip loops. Common mistake: trapping cables under the bottom edge, which makes them hard to adjust later. Leave the bottom edge accessible for cable maintenance.
