Hey everyone! I was looking for something to take up extra space in my living room and have always wanted a fish tank. I was on craigslist yesterday and happen to see this tank and cabinet with extras pop up for sale and decided to jump on it since altogether it was only 200. It is a 75 gallon tank and I am going to do freshwater due to what I have heard about cost of a saltwater. My first question is, since this tank has not had fish or water in it for probably at least a year what should i clean it and the rocks/decorations with? the tank looks visually pretty clean except for some cloudiness towards the top of the tank
