adding refugium, comments?

Did the sunglass thing and don't see checkering so assume good to drill.

Thinking the crushed coral or coral chucks for pods as when I had a DSB, always seemed more pods on the rock than on the sand.

As for the overflow, since don't really have the height for the ref to drain downward first, the bulkhead with face outward then pipe will run horizontal for a least 16" before turning down. Any problems with this for flow? Noise really not an issue as in the basement but wondering about that as well.

Maybe a mud refugium? Looks like a nice spot for mangroves as well.
(I'm biased.)

You would need a small baffle 2"-3" for the supply side.

Think pass on the mud, but have a piece of 4" thin walled conduit set aside to make a bubble tower.

No problem with the design...but insure that you have lots of overflow capacity in case that pipe gets blocked by something. You could have quite a flood down there before you noticed anything.

Flooding is a fear, which has me thinking, wouldn't be too difficult (in theory) to wire up a moisture sensor that would trip out the return pump if got a leak in the mech room. Would leave the CL running for circulation (aeration). Could also have in series a upper limit sensor on the sump, would save me from the wife and the tank from the auto topoff.

See often 600gph gravity for a 1" bulkhead, would that need to be reduced if mounted sideways?

well bulkhead doesn't work, details here with pictures and video.

Would it make any difference if you had more of down angle on the return.
Maybe by using flex from the bulkhead or raising the ref? Maybe the air could get out easier and give you more flow?
