Aquaclear 300 super noisy
Okay guys so I've kept fish for years now and have always used my trusty Aquaclear 300. Now this filter does have some age on it but works fine. But over the past month or so it's gotten super noisy. I know it's not the impeller being worn out because it was replaced maybe 3 months ago and I've checked it and it looks great. Is the filter on its last legs? I've also noticed if the water level falls slightly below the lip of the filter the amount of water it filters falls drastically. Can anyone help me solve this noise issue? Or give me some advice as to whether or not the filter is just going out. Thanks!
