Thanks for all the imput,The biggest thing I am concerned about is the noise the skimmer makes.Our tank is in our living room and is quiet as long as the skimmer is off.I want a better than good skimmer that is fairly quiet.From what I am underatanding is that ETSS make good large scale skimmers.However the reef devil is not up to par as some other brands? The ER skimmer is it loud, which is louder a beckett style or downdraft?
