I think there are a number of us on the board that have graduated from Engineering programs. I never found that school became any easier until I graduated and was done with it.
That said, if you are the type of person who can take a hands off approach to the tank, I would say keep it. You may get some algae growth, your corals may not grow as quickly, or expand as much, but it is good for relaxation.
If those things will drive you nuts and you have to frag out the large coral, clean the glass, remove the algae, etc, etc then I think you will find that you won't have the time.
