I noticed that my skimmer hasn't produced any skimmate since I emptied it last time about a week ago. I can't tell the reason though. It still seems to be pulling in air and water is flowing through it, just not foaming up like it used too. I don't think any surfactant or anything like that got into the tank??? I guess I should probably pull it out and clean it good and see if that helps before I run out a get a new one. ( Hoping to find an easy fix since it is a bit of a pain. Oh Well.
