The Backgroung is from Back to Nature link is www.backtonature.se/english/index
It does cover the Juwel internal filter, it called the Rocky Juwel and is designed to fit the Rio 180 and other models.
Zephan, the extra light fitting is Juwel's own, it comes complete with a set of smaller flaps for the top. Admittidly they aren't cheap, but when you consider how long your going to keep the set up, why get all scingy over a few extra quid ($ for the yanks reading this). I feel that once you have the hardware sorted out, the rest of the hobby, fish and plants, are relatively cheap. And the reward for the effort put in, is more than worth it.
The one thing that annoys me on this and all fish forums, is the way people criticise various products because they are expensive. In this world you get what you pay for. Buy cheap you Get Cheap. I have the philosophy, that if I can't afford it, then I will wait, save more and then Get It. Why buy cheap, if it goes wrong you eventually, through experience, have to end up buying the dearer product in the end anyway.
