Ive got the Eheim Classic 2213 external filter, The changing of the media is all good, but im not sure if the pump on the top can be opened up and cleaned out ?, once the grey housing is off what do i do next?
I had a quick look on google but found nothing, and i wanted to clean it because its getting noisy.
