Ok I am a college student. I now have a 10 gallon tank that is a freshwater tank. I am wanting to turn it into a saltwater tank for this summer and then move it back to my dorm room. I am looking at putting some live rock and some fsh in it. I bought the tank as a kit from petsmart. It came with the freshwater filter and hood and stuff. What am I going to need to turn this tank into a saltwater tank. I am only looking to put live rock in it and some fake coral and fish. What can I put in the tank and how much is it going to be. Thanks for the help and no I cant get abigger tank. Also would it be better if I do a nano tank with it? thanks.
