Coming from an old guys perspective, I love my reef tank and agree that it can have a calming affect. It can also a source of pride and accomplishment too. That being said, they require a lot of attention, even when you don't have it to give. I had a fowlr tank for 15 years. If the nitrates got a little high I could overlook a water change for a week without disastrous affects. A reef tank is not so forgiving. I set mine up 9 months ago and I found that I don't own the reef, it owns me. I still love it though. No one knows you schedule more than you. If you can run a reef between study, class, and dating go for it. If it becomes a burden though, it may no longer be a positive thing. Gook luck and success in whatever you decide.
