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).
