A kind of aquarium oil film processor,It is include ontology,Water-pumping motor group and floating shifting tube body,On the ontology,Lower two end systems are in the openning shape of perforation,And merging has filter material inside what,One Water-pumping motor system installs the lower end of the what ontology,To be drawn aqueous,On one floating shifting tube body,Lower two end systems are in the openning shape of perforation,The sliding upper end for setting the what ontology of its lower end system,And the inside of the what ontology is communicated,The floating upper end system for moving tube body is equipped with a plurality of blastholes,And what is fixedly provided with an enclosed gas seat,And the interior formation gas chamber of the what gas seat,To provide the floating buoyancy moved needed for tube body sliding is gone up and down； Thereby,Using enclosed gas seat,It can ensure that the floating long-term required buoyancy of shifting tube body,With with water level height and automatic lifting be drawn top liquid level aqueous,And then reach practical benefit.一種水族箱油膜處理器，其係包括有本體、抽水馬達組及浮移管體，該本體之上、下二端係呈貫通的開口狀，並於內部置入有過濾材，一抽水馬達組係裝設於該本體之下端，以抽引水液，一浮移管體之上、下二端係呈貫通的開口狀，其下端係滑設於該本體之上端，而相通於該本體的內部，該浮移管體之上端係環設有複數個入水孔，並於內部固設有一封閉式的氣座，而於該氣座內形成氣室，以提供浮移管體滑移升降所需的浮力；藉此，利用封閉式的氣座，即可確保浮移管體長期所需的浮力，以隨著水位高低而自動升降抽引上方液面的水液，進而達到實用的效益。
