I don't have a SW tank yet but want to get one. I have 5 FW tanks running. Yesterday I saw a 75 gallon with everything included for sale. It was set up and running for about 3 years as a SW tank so all filters, lights, etc are for SW. The person that knew the types of all the filters, skimmers, etc wasnt there so I don't know the particulars on those. The tank and stand were in very good shape. All this considered, would $300 be a good price or is that still too high? I paid $350 for my 75 gallon tank new and that was only for the tank, stand and strip light.
