I myself own a EuroReef RS 135 and a RS80. One is on a 75, the other is on a 48. I have been told by a few people unrelated to ER about how sturdy the older skimmers are in comparison to the newer ones. I had an impeller that the plastic needles were very brittle, and any cleaning resulted in losing more. Even missing about ten or 15 of the needles, I never adjusted it, and still pulled the same skimmate. I would get the ehiem and have Ace mod if needed.
