Looking for some guidance on what to do with the open cell filter in my sump baffle. Is is supposed to be cleaned and if so how? Attached is a photo of what I’m referring to in case my description is not clear. I believe the intent of this filter is mainly to capture and reduce transfer of micro bubbles from the skimmer to the main display.
It’s become discolored and is now a brownish color like a dirty filter sock. Should I be cleaning this regularly and if so how?
