It sounds like you guys change the socks quite often. My socks don't fill up all that fast and after 3-4 weeks water still runs through them fine. I have noticed that my water quality really degrades after about the two week mark. Maybe I shouldn't feed so much
. I am going to start changing the socks once a week and see if that helps. Has anyone noticed this problem if the socks are left on for extended periods of time.
