I sometimes run carbon in my tanks but usually dont. The sock will catch any particulate matter that is floating about and the refugium is just there to do its job as well. Unless you are experiencing any issues I would run it like it is.
I have plenty of carbon, at petco they had marine land carbon for only a 1$. I got 2 but if i run out i will just leave it out then
