DIY Airlift/Mammoth pump sediment filter

A simple airlift based filter to easely clean your pond or pool. It is simple, effective and, contrary to other sludge pumps, total animal friendly. I don't know the flow volume but it seems to be more than 10.000l/h at waterlevel If you build one yourself: Please don't use your filter overnight. Newts are really curious creatures and you will have ALL of then in your filter bag (unharmed but weakened). The list of all required materials: https://docs.google.com/document/d/e/...
