what level are you running it at?
I just saw the water level indicator on the stem. Im well above it... this is likely causing problems. This is my first skimmer. Ill get a skimmer stand to bring it up to the water level needed. I just assumed the red sea reefer sump would work well w/ the red sea skimmer ... w/out any adjustments or at least better instructions on how to install.
Thanks for the feedback!
