HenryC Posted May 11, 2021 Share Posted May 11, 2021 Has anyone had this problem with a fluval canister? I got my 406 canister for some time now, but a few months ago it started to do this horrible rattling sound, as if the impeller is hitting something, or is stuck, and then it stops cause the impeller cover falls off. It always happens after a water change, it is so bothersome that I've considering just thworing it to the trash and just buying an internal filter or even a hang on back. I just need it for mech filtration since I got multiple sponge filters. I even bought a new impeller, ceramic shaft, gasket and impeller cover but it still has this problem. I also make sure to expel all air and clean the impeller thoroughly before plugging it but this problem always comes up. It's always the same: Plug in - > work for 3 seconds - > CRAAAACACARCRCRC - > stops cause impeller cover comes off - > Open it to put impeller cover back up then rinse and repeat lol I'm on my wits end lol, now I know why Cory hates canisters. I've sent multiple e-mails to fluval but they #trippin and haven't got a reply. I'd be happy to have just sponge filters but I like my water to be clear so I need mech fitlration. Any suggestions?
