Beckett foaming venturi nozzle fountain head
For more pond aeration I recently tried out a pond fountain nozzle that a friend sent to me. This particular unit is called a foaming fountain head nozzle and it's made by the Beckett Corporation. It works on the venturi effect to suck air in and mix it with the water being pumped through. This creates thousands of bubbles in the water and greatly helps to agitate the water and oxygenate it which all helps keep your pond and fish in a healthy state.
Personally I still like to use my in-pond underwater venturi (the Beckett won't work underwater) because it creates a current in the pond for the fish to swim against, and play in the bubbles. Keeps them fit see!
There are some pictures on my main web site as usual showing the Beckett nozzle in use. Just click here for the Becketts foaming fountain head nozzle page, where you will find further information and locations where you can get this nozzle and similar ones from other manufacturers.
