My AquaC Urchin skimmer isn't pulling no skim... Just straight water. I just did a 20% water change 3 days ago and I cleaned the skimmer 2 weeks ago. I literally can fill the skimmer cup to the top in under 5 minutes. I have the cup set all the way to the top and I am not running a filter sock at this time. Any ideas? The only difference is I stopped running a filter sock. With a sock I would pull an olive green skim, without a sock I would get a dark green/black skim so I stopped running one. A few days of good skim and now I pull water... Any help is appreciated. thanks
