Venturi aeration of a small fish pond.

In this clip i show how i aerate my small fish pond.

I use a very small water pump, about 3 watt. a small piece of pvp pipe (used by electriciens) and a PVC elbow.

I heated the bend of the elbow and squeezed it so the flow of water would be restricted. Then i drilled a hole and inserted a straw/small piece of tubing. Because of the water restriction, an underpressure accurs and this sucks in air from the ambient and that gets mixed with the water.

So no need for a water pump and an aire pump.
Use your water pump as source to drive a venturi and your done.

Hope you like 🙂
