When i go away to school next year (likely U Wisconsin Madison), I am going to want a tank for my room. Maximum size tank in a dorm is 20 gallons and the 14 aquapod will probably be easiest for me. If I buy an auto-top off unit is there anyway i can make this work? I will obviously be away on some vacations coming home that will leave the tank alone for around a month once or twice. I was hoping I would find someone to take care of it for me when I'm away. If I don't do any dosings at all besides ph buffing and just get an auto-top off are there any corals that will still thrive with no additives? i was thinking xenia, shrooms. How about acans, rics, zoas? Also to anyone with an aquapod or smaller tank, is it that much more difficult to take care of then say a 75 gallon tank? I dont want to be overwhelmed.
