Ok so I added a tunze 9005 skimmer to my sump about 2 weeks ago. The issue I'm having is that my water level is about 1-1.5" below the water level indicator on the skimmer. I'm having trouble making it bubble high enough to get into the collection cup even if the air valve is all the way open. Does the water lever have to be as high as the line on the skimmer for it to skim and collect in the cup?
Any info would be great.
Cheers.
