When is it too big?

what are your thoughts on this?

I don't have a giant tank, mine is only 30"x24"x24" (LDH). But one of the reasons I went with this size is at I could use just 1 led light, but if I went with a standard 90 I would need 2. So one of the differences in an extra 4' (I assume you meant 120, not 100 ft) is extra lights, in addition to extra everything (tank, pump, rock, sand, etc). For me that would not be an insignificant extra cost. As for ongoing extra cost, there is that much more maintainance involved: water changes, vacuuming, scraping, and so on.

Clearly you are the only one who can decide what's appropriate amount of time and money to spend. I would find the prospect of running a tank that big daunting, but the prospect of looking at such a tank a treat.
