Ok so Ive had my reef octopus skimmer for about 3 months now. So it SHOULD be broken in. However unless my sump is filled up to the red line showed below, it will not produce any overflow into the cup:
It makes froth, just never reached the cup. To me that doesnt make any sence because i've seen skimmers in MUCH shallower water and be able to skim no problem.
On my skimmer I have this little pole that you can adjust up and down (shown in blue below). However, its not a tight fit inside the chamber. Its very wiggly and when I try to pull it up a bit, i feel like its going to slide right back down:
So what am I doing wrong?
