Well it worked, I have very few microbubbles left, and I believe those will go away with some time.
First I cut/drilled and mounted my M820 opposite ends of my return pump tunze style, then I adjusted in the intake on the back
Next I modified the return pump. I put a T in the pipe with a 45 on the bottom and a put sponge in the T bottom so that the airbubbles will get caught in that port, collect, then just rise right to the surface.
