sump or no sump

[DocLiette]

i have successfully had a 34 gal reef tank for the past 9 months. Everything is doing great. Coral growing, fish healthy. Calcium and other elements great. Nitrates, ammonia, phosphates all at zero.
No sump has been used.
I'm wanting to expand to a 75 gallon.
Is a sump necessary for the bigger tank, or just a convenience? I would prefer to stay without one if possible, just less hassle.
Thoughts?

On a smaller tank like your 34g it's a lot easier to get away w/ simple regular WC's, but when you step up and want to add gear a sump is awesome to have, and makes a lot less clutter in display, gives more options for equipment.
