I did respond to the PM, but for the record I'll comment in the thread, first by pasting my PM and then I'll add something about "noise."
I have a Rena XP3 on my 5-foot 115g tank. I've had it for over 2 years now. I consider it a good filter. As I've written in various threads, Eheim is about the best canister one can get, but Rena is a close second. Eheim have the reliability record; my two Eheim Pro 2's have been running continuously for 14 years without fault. Rena may not last like that, we don't know, it hasn't been around as long. I won't go into why I got the Rena, but at the time the majority of reviews ranked canister as Eheim first, Rena second, Fluval third. The cost of each reflects this order.
On filtering, the Rena certainly does the job. I have to rinse the pads every 6 weeks or they begin to clog. Which says to me that it is pulling stuff from the water. One drawback though is the length of hoses. They are five feet max, and as far as I know, Rena do not sell additional hose lengths. This means you can't have the filter intake or outflow further than 5 feet from the canister, so consider that when you are planning. If the tank is 5 or 6 feet length, the canister will have to sit in the centre under the tank if you are to reach both ends. Eheim don't have this problem as the tubing can be bought by the foot and cut to whatever lengths you require.
This is not really a noisy filter. My past comments were more in comparison. I absolutely cannot hear the Eheims running. I can hear the Rena, but it is not anywhere as noisy as my air pump. I don't really care about noise as I have a fish room; but if I had tanks in a bedroom, or living room, noise would be something I would consider--but the Rena XP3 does not fall in what I call noisy. I'm a light sleeper, but I could probably sleep with the Rena running as it would be continuous. The fish jumping would likely be noisier, and wake me.
