I've owned my Rena 200 now for 6+ years and am VERY happy. It's so quiet--almost silent. It is just now starting to loose some of its original power, though still performing well enough for my 30 gallon tank. I'll be replacing the diaphram with the rebuild kit and be ready to go for another run--maybe another 6 years. Great pump. The other reviews which mention the noise are NOT what I have experienced--like I said, running 6+ years now and all super quiet!
