Does anyone know anything about these skimmers? They have an insane price tag but i need a good skimmer and dont have room in my stand to add a sump that really limits you as far as skimmers go.Is it true you dont need to use a sump with it how would you do that just stand it up on the bottom of the stand and run a line to it.
