	Need help with new Fluval 404
NeptunesLady Hobbyist Posts: 71 Kudos: 197 Votes: 64 Registered: 29-May-2004	I cannot seem to get the air bubbles out of my new Fluval 404. It has been up and running for 3 weeks now. I have tipped it back and forth and side to side, and I have primed it until the water comes out the output tube. I don't know what I'm doing wrong. Can anyone help me?:%) Thanks!

When I hooked my Fluval up to my new tank, there was air bubbles. Took me about 2 weeks to realize that was because there was an air stone just about right under the intake!

I just don't know what the noise is, my husband says it's the motor and that I should call the manufacturer. I just don't know....:%) Thanks though, for the ideas!

NeptunesLady Hobbyist Posts: 71 Kudos: 197 Votes: 64 Registered: 29-May-2004	I just called Hagen, and did some testing, and it seems that the problem is that the impeller is hitting the cover. So they are sending me a new cover. I hope this works. Thanks for all the help

NeptunesLady Hobbyist Posts: 71 Kudos: 197 Votes: 64 Registered: 29-May-2004	My hoses are plastic too. Where would I buy rubber hoses if I still have a problem? Is this something you can get at the LFS? It doesn't look like Big Als carry these. Thanks
