Gixxer600- didn;t really read your last post. Mind letting us know you your setup goes, and how well that acrylic AIO fares in its first few months? It's a surpisingly inexpensive tank for what you get, if it works.
ATLWEB-
The Aquastyle 9's a nice tank...I've got one and it's coming along slowly but nicely. But I spent a lot of time and surprising amount of $ trying to wring decent performance out of that little corner filter unit (hint...it's exactly the wrong size for anything you'd like to put in it) and finding a lighting solution I liked the looks of. But the tank is incredibly quiet and a lot more flexible than I expected. Just not cheaper once the lighting changes and tinkering budget ended up tallied. ;-)
As a desk tank that has to cooexist with...work, you may want the Aquastyle 6, the Nuvo Nano 8 or the EcoPico. Either of the others comes with a better "reef capable" lighting option unlike the Aquastyle, and I think the NN's got a better filter design for accepting off-the-shelf nano medias (the small sealed pouch of Purigen, the mini-size baggie of Chemipure, Fluval Edge bagged carbon etc).
In an office, you're probably going to prefer anything with maintenance that is simplified down to "Rinse, Pop, Swap and Run". The Aquastyle's not that tank, from my experience.
