I am planning a 70 Gallon cube and plan on a mixed reef with a medium to heavy bioload. For different reasons I will not include a sump. How well does the comline filter 3166.50 reduce surface scum? I am thinking a skimmer of 9005,9006, 9010 or 9011 and adding the filter to run carbon and filter floss. Does this sound like it may work? Thanks for your input.
