I am thinking of getting a new (different) skimmer. My sump is small (the chamber that the skimmer goes in) It is only 7x15 I think. I think my best option is a out side the sump skimmer. Can you if you have a out of sump skimmer post some pictures? Plumbing etc. Would I just put a pump in the sump plumb it to the skimmer and put a return line from the gate valve back in the sump? It seams simple but I guess it is not that easy? Thank you Bruce
