I can't really see what's in Photo 1.

Do you have anything thats drawing in air and producing microbubbles? Is there any protein skimmer? Or is the canister return splashing water into the tank? Doesn't seem like the wavemaker is causing the bubbles here.

I can't really see where's the surface skimmer, is it the vertical tube on the right hand side of the picture?

I think you would need to reposition the wavemaker slightly, its pointing a little too high, I would suggest lowering the angle slightly. You can try getting a 2nd wavemaker to improve water flow, this can also reduce algae growth as well as improve aeration. Ideally, the 2nd wavemaker should be placed across the tank and moving water in a direction opposite that of the 1st wavemaker.
