Well it's producing pretty good skimmate now but here's my next question, how often does everyone clean the neck of their skimmer. I was cleaning it every time I emptied the skimmer (about every three days.) for the last two weeks I have just been emptying the cup and not cleaning the neck and it seems to be producing more skim than before. So how often does everyone clean their skimmer's neck I don't care if you don't have an octopus I'm just curious.
