Oil film remover/Skimmer/出水口除油膜/撇渣器

Venturi tube principle to remove the oil film on the water surface, prevent suction fish suction shrimp suction grass, the effect is very good.
Adjustable, you can scale it yourself, or build one that suits you, let me introduce you.
As far as possible, the other end of the original water oil removal film mouth is sealed to avoid suction into the biological filter.
There are a lot of aquarium related designs waiting for me to upload slowly...

文氏管原理去除水面的油膜，防止吸鱼吸虾吸水草，效果很好。
可调的，也可以自己缩放一下，或者自己建一个适合自己的，我这抛砖引玉吧。
尽可能把另一端原本的下水除油膜口封死，避免吸到生物进过滤。
还有很多水族相关的设计等我有空慢慢上传…
