➤ Design and function Zhongke's protein skimmers are designed as filter system which material of a common filter system is replaced by air bubbles. The function is water enters the protein skimmer at the top and flows down to the bottom. The air is introduced near the bottom by sucked in by an injector (venturi) and small bubbles rise against the water stream to the top. The airflow should be sufficient enough to fill the cross area of the protein skimmer.
