ok one thing i notice about the Tunze skimmer, whenever i feed cyclop-eeze plus zooplanton the foam level drops for like 10mins then rises ... my weipro's foam on the other reacts almost immediatelyand never drops til all food gone. Its almost like the Tunze pauses skimming for a few minutes to think it over whether to skim away good food.
guess this statement Tunze made about their skimmers is true afterall
