3-16 Inch Aquarium water pump venturi.

A venturi that I designed as a replacement for the 3DPONICS 2 air intake Conduit. This venturi works better from my tests for water flow and uses only one air intake which leaves you with an extra air outlet from the pump to run another column or an airstone etc.
I did measurements on both this venturi and the conduit and I am able to draw about 10% to 20% more water up an 8 ft column with this unit.
Not saying either design is flawed but both can be improved upon. I want to thicken the wall
