Hello everyone! I’ve been having issues with my protein skimmer that I cant find anywhere online. First off, I'm not collecting any skim. The foam only moves up about 2 inches from the water line (pictured below) I clean it out regularly but that doesn't seem to be the issue.. I’ve had the tank for around 9 months and it was working just a couple months ago. If anyone notices anything i'm doing wrong please let me know.
