Clean the walls of the aquarium thoroughly. If there is a lot of foam afterwards, it means the foam filter is working fine; it just has nothing to remove right now.

I checked the pump again, cleaned everything that could be cleaned, slightly changed the position and water supply - the foam is pouring out like crazy. Apparently, it missed the skimmer overnight. However, I couldn't clean the internal buildup. I ran vinegar for half a day but didn't achieve the desired result.
