I got my Fluval 304 delivered today. I just finished setting it up, which was not as easy as I expected. Seems the directions are not 100% clear and they left ouf some parts in the process to setting it back up.
Anyway, I figured it all out fine, its up and running now and amazingly quiet. The primer sucked, that took a while to get started, but once water was in and I could plug it in, it was good.
Also, for those that say it takes a day for it to stop making noises...remember. There are bubbles in there still. I wacked mine left then right then forward then back a few times, basically rocked the air out of it - instant quietness.
I have a rubermaid box under the filter for safty sake while its getting started. The connections were a bit shabby. Just feels scary to have it just pushed together like it is and not feel like a tight click in feel.
