The only thing I'm missing in my system ( or so I'm told) it a protien skimmer. I have a Berlin right now but it not running. I'm looking for opinions. Should I put the berlin in a sump/ ref below the tank or forget about the sump/ ref altogether and buy a hang on the back. What are the pros and cons of each.
