Those EasyPond skimmers are neat -- hadn't seen them before! The only in-pond ones I could find had an outlet that you have to attach a hose to the inlet of your pump (so, the pump sits OUTSIDE the skimmer but draws water through it on its way to the pump). I'm going to add these skimmers to list!I have cages on both of my skimmer pumps. It helps keep out any larger stuff, and I swipe them off when I have to clean the mesh filter. Just have to make sure the pump you get will fit inside the skimmer you buy.
