Anyone using a Nanostream 6055 on a multi controller?

[Todd]

What is the fish care function? It always says that they have fish care function, but never what it actually is.

I am planning on replacing my Seio 2600 with one Tunze 6055 right now (mabye on a profilux system....). I currently have a 75g tank (4' x 18" I believe). But am thinking that I may upgrade to a 105g tank (6' x ? x Shallower then normal), and then adding an additional 6055. I just think that the Seio 2600 is too loud and too big. So that got me looking at the Nanostreams, then at the multi controller, then that got me thinking 'well a profilux isnt that much more then a multi-controller, and I may want a profilux in the future'. And like everyone says, its alot cheaper to do it right the first time.
