Is it mostly the same for any size tank.  Your stuff just takes up a bigger space.  

  I think most people with "top notch" reef tanks will spend 3-4 hours a week doing fish related stuff; from feeding to testing, dosing, making new RODI water, mixing saltwater, etc.  Some people have a lot of things automated though, and they have the luxury of spending less time maintaining the tank, and more time staring at the tank.  This luxury comes at a price.  There are some OCD'ers out there that spend 
a lot more time than that, but I don't know any of them.  

  You can get away with an hour or two a week, but don't expect diamonds when you're only panning for gold.
