Everyone has experienced it before: a noisy aquarium filter. Quite annoying, especially if your filter is not inside the cabinet but outside or against the glass of your aquarium. But how do you make your filter whisper quiet again? Some like to use Vaseline, but I prefer a silicone spray, which is a bit greasier and also gets into the hard to reach places.
A quiet aquarium filter in 7 steps
Here’s how to proceed:
- Disassemble the pump. Be careful with plastic parts
- Remove the impeller and other loose parts
- Rinse everything thoroughly to remove debris
- Scrub all parts well to remove brown algae & other debris
- Rinse again
- Lubricate the moving parts with silicone oil (in spray or a tube). On most aquarium filters, you can lubricate the “rod” of the impeller along with the rubber ends. Do not forget the other parts
- Put the filter back together
- Before putting the aquarium filter back into the tank, test if you are satisfied with the result. If not, repeat the steps above. If that still doesn’t solve anything, then I’m afraid the impeller of your aquarium filter (or another part) is damaged. I recommend replacing it quickly.
