Seaview Background Mounting Gel is the perfect accompaniment for any of our excellent backdrops.
It securely and easily attaches the background to the back of the tank, and allows the maximum amount of light through. Compared to household glue or tape can distort the amount of light than penetrates the tank.
It is easy to apply, non-toxic and even better, easy to remove. It won't be affected by salt either, so you can be confident of long lasting results.
A 1oz bottle is sufficient for a 75 gallon aquarium.
