I have an old CS6-1 on my prop system; same dimensions as the current RS100. My skimmer really started to skim when I swapped the stock 3500 Sedra for a 5000. Also added the gate valve, as it had the original telescoping output that was a pain to adjust. I always thought that the pump was too small, and noticed a huge change in efficiency after upgrading. Kinda sucks that it didn't come with a great pump to start with, but I'm very happy with it now. If you can get ahold of a Sedra 5000, try it out; you won't be disappointed. Also have a RC 135 on my display tank, and am very happy with it. Enjoy your new skimmer.
