I am looking at a 130G SW tank. The left side of the tank has a very large overflow but houses two large 21" (carbon??) filters another media filter and has a built in protein skimmer. Is this enough for the tank to run without any external add ons? The tank has been setup for several years with no problems but I want to turn it into a reefsystem down the road. The guy Im talking to says he had quite a bit of coral in it but sold them about a year ago due to lack of time. The fish and the live rock all seem very healthy so it has to be doing something right.
