I have (had) a Fluval 403 I bought 5+ years ago and I have been very happy with it, but had a power outage yesterday, and it stopped working. I have taken it apart and put it back together, plug it in, and still no sound from the motor. I'm pretty sure it's dead. So time for new canister. It appears both the 405 and XP3 have gotten praise, but the Rena XP3 is cheaper. I also have a pair of Powerhead 802s for water movement. What is your recommendation on which canister and why? I am looking something that has been as quite as my old 403 (couldn't hear it with the cabinet doors closed). Thank you for your input.
