Airlift: How to build - Part one

This is the English version of the Airlift build tutorial by Marc Criel, part one. The original video was made possible by Patrick of Aquatechnobel. This video shows how to build the best Airlift design for gravitational ponds, as developed by Marc Criel and several members of the Belgian site Koivrienden.be. Subtitles by Pssymon. I added some asterisks where information in this video was no longer up to date. This video is three years old and a couple of things have already changed. - 2:41 : 170cm is no longer considered to be the best depth for every pump, when using a 20W airpump a depth of 145cm has now yielded a return of 20.000L at 12W. Tests are still ongoing. *2 - 16:03 : Again, a 20W pump can give a higher return at a depth of 145cm, with the same relative power consumption. *3 - 16:26 : This has now been proven to be higher, 15.000 liters per hour at 9W. 0.6W per 1000 litres. *4 - 22:07 : This is no longer an issue as a member on Koivrienden.be succesfully runs a drum filter with an Airlift. Benefits of this system: Huge water displacement at a fraction of the energy consumption seen in regular water pumps. Effective aeration and water displacement combined in one system. Tests have showed up to 20.000 litres per hour displacement at 12W, up to 15.000 litres at 9W. Can also be used as a protein skimmer. The Airlift has no moving parts, it cannot break down and requires little maintenance. 110mm inlet means clogging is almost impossible. Wildlife cannot be harmed by moving parts. Inexpensive and simple to build.
