[daiandgems]

Hiya ive jus set up my new tank which has a fluval 405 but its really noisy can hear it running over tv and in other room.Ive done all what the book says primed it to get all the air out of pipes went slighty quieter but not a lot so let it run for a couple of days see if it would settle down but no such joy so am i jus presumming this is how noisy they are as its my first external if any one has any info/help id be greatful cheers Dai.

still sounds like its got some air left in the filter as my 405 is near silent

also make sure you have filled the filter right upto the top or it will start leaking

oh and how much is the flow running at?

If its just air, you can pick it up a little, tilt the top about 10 degrees in various directions and give it a little vibrational shake. I like to do this just a little bit at first in case there is a lot of air, that way I won't have to re-prime. Should work with any cannister filter.

From as little as 5 feet away, you should not be able to tell whether an external, what I usually call a canister, is even running. I cannot tell from much closer than that on my Marineland C series or my Rena XP series filters. The Fluval x05 series filters are also reputed to be quite quiet so there is something not right about yours. I would start by tilting the filter body this way and that to completely remove whatever air bubble is causing the noise. If the filter goes quiet for a while and the noise comes back, check all of the inlet connections looking for any sign at all of an air leak path. Even the top gasket that is used where the motor head joins the rest of the filter is a location that can introduce air if it leaks at all. Something is causing your filter to be noisy and it is not at all normal for such noises to persist over time. Instead, you will need to play detective and find the inlet side air leak that is causing the filter to become noisy after you once get it quiet.

will have a look later at all pipes to check for air leak and tilt filter back and forth see if that helps thanks

Just done a forum search and noticed this because mines doing it as well. Put a new impeller cover on it as i thought it was the old one being worn out, but its made it worse!!
New impeller is my next move, i think...

ive checked mine for air leaks and all pipes and none found tilted it back and forth to make sure no air pocket inside filter but still its noisy seems to coming from the motor impeller so its back to the lfs for mine i think see what they have to say

LFS replaced mine for a new one and i now have a quiet filter at last the other one wasnt sealing properly causing it to suck in air thus causing the constant air lock making the noise so its on with the rest of the set up now happy days

Nice one...Well done matey!
Can i ask where was it leaking? Mines still a little noisy...

 

[daiandgems]

It was leaking around the main seal between canister and lid and everytime water passed a certain level it started to trickle out of the back hope you have luck with yours (ENR) sounds like could be impeller not sitting right or could be like mine theres air getting in somewhere.

Thanks captain....changed the impeller this morning and after shaking the air out of it and then putting some foam rubber underneath it, the noise has abated a bit. You can still tell its on and running, but its a WHOLE lot better..

Anyway, thanks for letting me crash your thread...
Hopefully its sorted now...

Glad to hear yours is a lot better mate and a lot quieter.
