I may have read this wrong, but if youre leaving in 4yrs for school, why bother with a SW tank... some hobbyists take 5,10,15 yrs to establish their tanks with the things they want. I know this is different than throwing a HDE in a 125, but why do that if youre only hanging on to it for 3-4 yrs? Makes no sense to me. Get a nano tank if your serious about the hobby and take it with you to college if you must have SW for that period of time. If not keep the tank empty till your done with school and enjoy the hobby for the rest of your life when youre done partying in school (I mean studying)
