Fluval 404 Help

[Brian1f1]

Good morning!

I woke up to find that my trusted canister on my quarantine tank had stopped flowing and was rattling. I shook it and tapped it and it started and stoped in fits. Finally after about five minutes and a hard shake it started working, and seems fine. It’s not overly load and not rattling. Maybe a little louder than normal. I’m afraid it might seize up again, and I’m at work. I want to order a replacement part to be overnighted, but not sure what to get. I didn’t have time to open it before work. Anybody know what it would be from my description? I’m thinking impeller?

Sounds like buildup on the impeller or inside where it goes. I’d strip it down and 50/50 vinegar soak it for a few hours.

I don’t know. I went ahead and ordered the full maintenance/replacement kit over nighted. Worried about getting through the next day. Will see.
