Don't get a tank unless you are 100% sure you are never moving out.
If you decide to go forward... Think of the logistics necessary to take it apart and out of your home. For some ****ing reason, it was not a easy as it was putting it together. My 2 cents.
Well for starters...when putting a system together everything is dry and you're not dealing with live animals..... be it coral and/or fish. When taking things apart you have water, animals, sand etc. to deal with. A whole other story.....not as easy (I agree).
