Works awesome. You can skim dry or, I prefer, wet. The key to the tunze is keeping up with your top off water. This is very easy with the RSM because the evaporation is very slow. If the water gets noticeably low then your skimmer will perform noticeably less. The Tunze has a line printed on it that shows where the water line should be. You can lower or raise the skimmer in the back chamber to your desired level, then just make sure you top off your water every other day or so.
My buddy saw mine perform and purchase the same for his RSM almost immediately.
