instead of pulling the airline on my skimmer I always just take the cup off and let it over flow back into my sump. That way my O2 levels do not take a hit from having the skimmer off for too long.
now that's a great piece of advice right there. that's what i do whenever i do water changes and don't want to disconnect or turn off my skimmer
