oh, i haven't used a cone as of yet. to be honest, i don't see how it could be enough of a difference to warrant getting one. i was speaking from a business standpoint.
actually, now that i think of it, the rep from eshoppes let me borrow a HOB
cone skimmer for my coral tank at MACNA in atlantic city.. it reminded me of a coralife SS 65 really.
if i could quote him, when i asked how they performed in comparison to the old design, he simply shrugged his shoulders and said "eh, they make cone skimmers, so we make cone skimmers"..lol.
