My skimmer has a coating of Diatoms on the inside of the skimmer. No hair algae though. I really only clean the collection cup weekly. If I get gung ho I may clean the skimmer body once a year but I wouldnt say it's nessecary....
If your skimmer body is full of hair algae then a cleaning may be a good idea but if it's only a few patches I would leave it.
