RDWC with air lift pump for circulation?

How would an air lift pump work in a RDWC system? I can't seem to find any examples. Maybe I'm not searching the right keywords? Should keep O2 up and provide a slow recirculation. Planning on building multiple systems with 2- 5 gal buckets and 10 gal res's. Want to do an air lift from res to each bucket, passive returns.

It is because I am thinking about using a non return valve which in the reservoir which has AISI-302 grade parts. I don't know how aggressive the nutrients are to metals and if this kind of stainless steel might bleed toxic stuff into the reservoir.... Any idea? April 22, 2019 at 04:01PM Read more about this fix

How to correct Rising pH/PPM runoff

Okay so this is my first run with Hydroponics. I have been running a top feed drip line system. I am running my girls in 6 inch rockwool cubes placed in 7 x 7 pots filled with hydroton. There almost 28 days into veg from seed. I've begun to notice a couple rust spots on my girls nothing too major. I figured starting a little nute burn. So I backed off the nutes a little. I've been keeping track of the runoff and two of my girls now" the ones that are showing the rust spots and a slight droop...
