are you Running tank with out filter sock

[Trabby]

No sock, no skimmer. 90g mixed reef.

I use a 7 inch 200 micron filter sock on my reef. It prevents any leftover food or detritus from building up in my sump or damaging delicate pumps and equipment.

I only use it to keep the bubbles from the downflow contained and not create salt creep everywhere.
If I could find an alternative I would get rid of the sock.
I end up catching lots of pods and baby brittles etc in it =(
