Good day, dear marine aquarium enthusiasts.
The question is: we have a Herbie overflow, everything is working, the circulation between the display and the sump is normal, but debris (suspended particles, etc.) does not go through the shaft into the sump (the shaft is external). It just floats around the aquarium.
The video is too large to upload, I will attach a photo.
Thank you in advance for your advice.
