I literally typed subtitles for most of the video and then accidentally hit backspace outside of this box, so that's deleted now. I can summarise pretty quickly. He is testing the performance of this Airlift with a discharge head of 20cm above water level and after that, 25cm above water level. First he connects a 40lph airpump at 20cm head, then a 60lph pump, then a 120lph pump. After that the height is raised to 25cm above water level, showing the 120lph pump result first, then 60, then 40. He also mentions that this is done with an Airlift with a 180cm lift tube, the pressure chamber was postitioned at around 160cm below water level. (+20cm head = 180cm, the entire length)
