I have had a freshwater tank for about 6 years now and I have an extra 75 gallon tank that I did have freshwater fish in but it is now empty. I have always wanted to do a saltwater tank. I know it takes a lot more work. I just wondered what kind of start up costs I would be expecting and if this is a good size tank for saltwater. Thanks in advance!
Also, do I use the same filter or do I have to buy one especially for salt water?
