Your plan sounds good and what I would recommend.....the plants are going to like the higher mineral content new water, however, I would bring some water from home to use for fill up...about 75% home water and 25% dorm water to start-then make 25% weekly with the dorm water to get them acclimated to the harder water...this will help both the plants and the Betta adapt...
