Okay, so I made an air lift that actually works. There are a few things I will do differently with the final model on the tank. I will touch on those after the pictures so you can understand what i am talking about.
Outer Coupling 1.5"
Coupling and 1.5" to 1" bushings cut down
1" standpipe with small holes drilled. very small holes
The coupler with bushings installed over the drilled portion of the pipe
The coupling withe airline connectors installed
It actually working with very little depth to build pressure
This is all being achieved with less than 14 inches of depth to provide pressure for lift. With my aquarium and some inventive plumbing i can get upwards of 4 feet of depth pressure to work with. Which means I will be able to lift water easier to my desires height of about 9 to ten inches, maybe 12. This is all done for less than 9 watts of power. I don't have to worry about a pump failing or something clogging it up either as it is a smooth 1 inch all the way. In the model that i build for the aquarium i will change the 1.5" coupler to a bell "t" which will give me a much better way to connect my airlines to it. since I can cap the t and install the lines on a flat surface. I will also use screw in airline fittings. I may increase the pipe diameter to 1.25 since I have two 1" overflows to feed it. This in theory should give me better lift and more flow. I can also increase the airflow with a larger pump since I am only using a 140gph pump.
So what do you all think?
