HAHA, TSN is DEFINITELY taking advantage of the fish only policy lmao, thats awesome though not many people can say they have TSN in college dorm lol but yeah i could see not wanting to put it into main tank right away especially when you aren't there to monitor it regularly, thats crazy though about the dorm water, i would think that water that bad wouldn't even pass inspection... when i had a tank in my high school dorm i would sometimes bring gallon jugs of well water from my parents place, and when i had baby turts in my college dorm freshman year i used one of those brita filters and did little daily wc, but i doubt brita filter would be good enough to get metals and stuff out
