All I can say is WOW! One of my many "Tank Projects" for this weekend was to do the mesh mod to my skimmer. What a difference it made, you can see in this picture about 2 hours of skimmate that is like tar. While I did this I also decided to redo the plumbing. My overflows used to go right into a filter sock. Now the go right to the sump in an effort to keep crap suspended more, then the riser tube of my skimmer now feeds into the filter sock. I'm hoping this also helps keep the filter sock clean longer. I also took the hoses off of my phosban reactor because I was (tired of them kinking) and hard piped some PVC. I can't believe the difference it made in the flow. It is a much more even flow.
