Does anyone use a filter sock to catch microbubbles from their overflows? i have a slight microbubble problem from my overflow drains i was thinking of putting a 100 micron filter sock around them to try and eliminate this problem. one question i have though is won't this defeat the purpose of the skimmer? or will this actually help the skimmer out by removing large stuff and allowing the skimmer to do the job on the rest?
