Yep checked the website and came up with this:
Oceanvisions is a vinyl, waterproof, "sticker" background that eliminates water stains, salt/lime build-up, dirt, and other foreign debris from EVER appearing on the rear glass of your aquarium.
* It replaces dull weedy backgrounds with vibrant color...
* It is easy to apply- no tapes or glues...
* It comes in 4 widths to fit almost any size aquarium...
* It is waterproof and will last for years...
* It is easy to remove when you want to redecorate you tank with a new Oceanvisions look...
Fishkeepers love Oceanvisions adhesive system as it achieves the same intense clarity of a solid color acrylic backed aquarium. Since it adheres to the glass, it will always appear clean and new!
Oceanvisions are truly a unique product that is head and tails above all the rest. The mirror style gives an intense, clear image that makes your tank look double in size. The other colors are vivid as well. We have observed them over time and they DO maintain themselves well. They do not breakdown or fade. They will last as long as you need or until you replace one with another to give your tank a brand new look again. Try them out, you will not regret it!
NOTE: You will need 3-4 inches of room to install an Oceanvisions background on an existing setup. If you have a small setup with hang-on filtration you may need to remove these items to install the Oceanvisions.
