That looks like a new system with new plumbing. Give it a
couple of weeks to slime over, and you'll probably have very
little compared to what you see now.

Your sump layout looks good to me. You might try turning
the inlet of the return pump toward the left wall of the
sump, away from the bubble trap. You can put an elbow
pointing downward on the inlet, so that it sucks water from
the base of that compartment.

If you still have microbubbles, your return plumbing may not
be water tight, and a little air is being sucked in.

I'm back again with my next glitch *sigh*. I'm getting a large amount
of microbubbles back into my display tank. I have baffles installed
after the skimmer section and before the return section. See pic

As you can see, I even added another baffle before the return to avoid
the waterfall effect.
It seems that I have so much flow through the sump that the
microbubbles never have a chance to surface and pop and are being
forced through all the baffles and back to the return pump. I have no
liverock and I have just been circulating sw through the system. Will
this problem subside once I stock the tank and sump with liverock or
do I need to stick some floss or a sponge in the last baffle? I am
concerned about creating a nitrate factory with the latter and
possibly restricting the flow too much. Did I maybe select too large
of a return pump (mag 9.5)?

Just wait, someday I will have something to contribute here instead of
pestering everyone with questions. Thanks for your Ideas...again
