a MJ 2100 is prob overkill, Im using a 900 ad that is also feeding a phosban reactor. and it will prob take a week or to for it to slime up. Here is a pic of mine and I have had it for 2 years and love it. The white pipe is the return to the sump so mine is CC
Oh if you can make a waste colector that will shut the skimmer off, I made one, but dont have a pic since CC skimmer, but I do have a link for it
