Jungle Bob 3D Aquarium Background 36X19 Inch For 38/50 Gallon Thin Grey 8298
The thickness of background is only half of inch.
The exact background size is 34,4 x 17,4" in 2 sections - please compare it with your aquarium internal size.
1. Insert both sections of background inside your aquarium
2. Connect both sections with black tabs provided, squeeze both sections together (gently)
Optionally: If you want to make the seam less visible you can use a clear silicone (safe for fish) to fill the seam and squeeze well. If wish to use silicone, you have to drain your tank and wait 48 hours to cure the silicone.
***Note- Measurements represent the back of the specified tank size(s). The background will be slightly shorter than the tank to allow it to fit within the support braces and plastic/glass trim around the tank edges, and allow it to stand up against the back. The difference in width is occupied by mesh to prevent fish from getting behind, and the height can be adjusted by leveling with gravel or small slate pieces. It can also be modified or trimmed using a dremmel or sander tool if needed.***
