I was lucky enough to find somebody giving out a 60 gallon salt water tank with cabinet and 15 gallon sump/refugium for a great price... Free! My fiancee was out of town for a couple weeks, and knowing she's wanted a saltwater tank for a while now, I decided to keep it salt water instead of converting it to freshwater. I set up the tank, wrapped it up, and awaited her return. She loved it, and once the cycle is complete, the fish will slowly trickle in!
