Compost Tea Brewers

Just finished up my first air lift brewer and gave it a test seems to be working as it should,I’ll give it a proper test tomorrow and measure the flow to make sure it actually is going to work. Any one with any experience with air lifts or any other types of brewers feel free to give your input or share pictures of your brewers. I’m hoping this one will be able to properly brew 200L (about 50 Gallons) the pump is rated at 200L per minute,manifold is 50mm pvc (2inch) and the inlet pipe is 25mm (1inch).

Would like to add this is in no way my design,it’s stolen from

I made a hex lifter and quad lifter. Vortex brewers. I only need 2-5 gallon brews so I scrapped them and just submerge airstones now. I would like a permanent vortex brewer but cleaning is annoying for indoor growing. So, less parts the better. Your design seems pretty good, I may copy it smaller and see how it performs.
Ps cock the spout at an angle for less splash and more spin

The splash I don’t mind but I like the idea of getting some rotation going,definitely will try that thanks for the tip.

Gave it its first wet run today it’s putting out a litre in about 3 .5- 4 seconds. I’m pretty sure that will be enough to keep decent dissolved oxygen levels,I still need to modify the outlet nipple which will increase output aswell.
