    What does the skimmer ratng refer to? The amount of water in the system it can service or the amount of water it can skim in a period of time?

    System volume.

    but IMHO its not a exact science, but mealy a guide line, as it also depends on the bio load and corals you want to keep.

    I have a skimmer (rated double my system volume) but the skimmer must then match the retuen pump volume (or 50% in my case) as this determines the amount of water flowing through the skimmer via the overflow. I suppose the connecting up of the skimmer also heavily influences the actual rating.

    So with a skimmer rated for 1000litres,what size pump would be needed to properly feed the skimmer?
