Hi, I am new here. I have had SW tanks in the past with out a lot of success and finally just gave up on them. I had a 55ga then sold it and got a 180ga. I thought it would be a lot eiser to control water qual. with that big of a tank. I still had a naso tang and 2 clownfish go on me. Now 3 years later I have decided to start up a 55ga again but cannot decide on salt or go with a ciclid tank. what do you think?
