3d aquarium backgrounds

[Anne81]

Hi All, just wanting some feedback about 3d tank backgrounds. I've got a 4 foot tank on order and was wanting to put a Juwel 3d background in, but was wondering if anyone has had them and had issues? Also are they hard to remove in future? Thanks!

I've never used them but been told to check on dead spots behind them.
