Skimmer Upgrade Required?

[SeaSerpant]

How often do you empty it? I empty my nano remora everyweek and i only get about half full and it's only a pale brown. The colour of the water is relative to how big the collection cup is and the amount of gunk in the water. When a person puts a new skimmer on usually it's because they haven't had one on the tank before and it has a lot to take out.
