emilyalice91 3 Posted April 4, 2017 Hey every one! Filter maintenance question today. So I have a fluval 306 canister on my 55 gal. It's been awesome ever since I set it up about 9 months ago. This last week I took it apart and cleaned it out during a water change. Didn't do anything different than I usually do and ever since that cleaning day, it has been so freakin' loud! Sometimes it rattles for a bit after I do any maintenance on it or change any of the media, so I usually give it a day or two to settle itself but the loudness didn't stop this time so I took it apart again to make sure I put was everything in place properly and it's still doing it! Has any one else had this problem? Or does it sound like it she about time to replace a part? Any advice would be much oblidged!! Thank you 0 Quote Share this post Link to post Share on other sites
