I've got my skimmer inside my sump and I'm not getting it to operate properly. Does the water height around the skimmer make a difference somehow? The discharge tube has a bubble diffuser (Coralife 220) that outlets properly (I believe). I just haven't gotten any skimmate or anything since I put it into service a week ago. I've adjusted the water flow into the skimmer and I can watch the water rise and up into the collection cup and overfill. I'm just not sure what I'm not doing right. I'm at work right now so I don't have a picture handy. Thanks!




It's been on the back burner since we had our daughter 3+ years ago....the tank has suffered a bit for it, as you might imagine. Considering that, it's actually in great shape.
