I have a Rio 125 upstairs, in the same room as the huge 450L tank, and also a 28 inch TV. I have (obviously) no problems, touch wood. As long as the tanks are positioned accross the struts properly you should be fine mate.

Yes Juwel are the best. German reliability and effeciency. Comes as a complete kit and you cant go wrong with the equipment for the price. I made my own stand, the internal isn't that difficult to maintain. :good:
