3D Aquarium Background

[The Duke]

I have just bought a second tank - 3ft long. Priced up the juwel 3d backgrounds and wow are they expensive. Looking at about £60 for my tank.
Alternatively, I have found some vivarium backgrounds which look even better and would be a third of the price!! Has anyone any experience of the vivarium backgrounds in an aquarium? Are they made out of the same material as the juwel backgrounds and are they suitable for fish tanks and to be submersed in water??

I'm sure there's someone on here who uses them and they're absolutely fine.... In fact I know there is someone as I was looking at it only a few days ago.
