I currently have a Marineland protein skimmer which i'm so close to punting across my yard. In the last week i've spent literally hours adjusting the damn thing. Won't hold adjustments through changes in water level. Have yet to get it adjusted after putting in makeup water. I've been at it for the last 3 hours. Also, it spends most of the time dumping foam into the collection cup filling it up in under a minute. I'm tired of babysitting the thing. Anyone have any suggestions?
