Does anyone have recent experience with the Eheim Surface Skimmer? I have seen at least one post in the archives that was negative about it. (Maybe they haven't changed??) I have an Eheim Filter and would like to add the surface skimmer. ( I know the majority of you are death on Canister filters but I come from the old school and have always had good luck with it) This is for my 46 gal bow front. Thanks for any help.
