Aeration Venturi Nozzle - 1 Pack

For its cost and size it works well. It adds apparent power to the water pump. Beware it's a 2 part device any excessive psi will detach the parts, a bit of F4 tape fixes that.

Works great and screws right into the little submersible pump i bought.Easy dissolved oxygen for watering plants.

Although i am not using this as a vacuum.. i bought this to explain to students how the bertoulli effect operates.. the fact that it is clear/see thru...makes it easy to explain the science !

The media could not be loaded. It takes a big pump to get a lot of air, but it definitely works!!Very nice
