Adding Air To Spa Jets

So long story short, I have a small gunite pool that I built 3 years ago (pictures included below). I designed it to be a small pool / spa with a bench that spans half the pool. I put in 7 inlets for jets using 2" pipe. I put in standard 3/8 eyeball jets. I’ve been wanting to add air to the spa jets but don’t fully understand the process and hoping that I didn’t miss something during the build. I bought a blower thinking it would be easy to mix the air with the water but that hasn’t gone well at all. I put a T in the PVC to the spa jets to add the blower. I’m feeling that I’m doing something wrong and that I’m not understanding how to accomplish mixing air and water. Hopeing someone can explain the air mixing process and if it’s possible to retrofit my blower to accomplish what I am wanting.
