I swapped from an internal to an external filter, but was surprised how noisy it is.
Using my phone to measure it is normally 40 decibel. The noise/vibration seems to come from inside the plastic lid and is kind of a humming noise.
If i lightly touch the lid, to stop the vibration, it is 30 decibel. (as measured by my phone using decibel x app). For now i have placed a small rock on the top to make it quieter.
I looked at impeller, it seems clean and fine. (I never opened it before installing it, so should be like from the factory)
Am i expecting too much, or is something not right?
