Honestly I would set up a small pico/nano on your dorm and not set this up at your parents if you are there only every 2 weeks. A lot can go wrong in two weeks. My freshwater planted tank I could pretty much ignore for months as long as the fish were fed... saltwater is another game, especially a new set up and not an older aged one.
If this is FOWLR then it would not be too bad but if you start playing with any sort of stony LPS corals, get any decent amount growing and now you brought testing and daily dosing into the equation.
There are numerous posts asking for help how to fix this or that or tried this and that and don't know whats wrong. I would never want to subject my family to that sort of stuff for the next 2-4 years you are in college.
A small tank in your dorm you can maintain and enjoy and do whatever maintenance it may need would be a lot better IMO.
