I've got an extra 10 gallon tank sitting around and I was wondering if I should set up a saltwater tank. I've done a good amount of research but I definitely realize that saltwater is in a league of its own and there is still a massive amount of info that I do not know. I understand cycling coming from freshwater and I've researched live rock/sand, different types of filtration, stocking and feeding. I'm going away to college in August where I would be able to take the tank but from what I've heard it's not the best idea to have a fish tank in college esp a reef tank. So, if I were to set everything up now I could have the tank until around the end of July at which I'd need to break it down and sell most everything. Currently I have the time to spend an hour or so a day with the tank and even more on the weekends, so that's not my biggest problem. What I was wondering is would it be a good idea to set up a reef tank now only to tear it down in 6-7 months time? And would it be doable under a few hundred dollars? From my understanding a HOB filter with a protein skimmer is enough and a secondhand light is probably the biggest part of the budget, since my parents would help with the cost of livestock. Should I stick to freshwater or is now just as good as ever to jump into saltwater?
