the oxygen depletion from the algae must not be that bad because I have tons of macroalgae in my tank and I shut down my skimmer at night. No problem what so ever. I really have lots of caulerpa. When it goes sexual all my water become cloudy white and sometime I wake up to a very cloudy tank but nothing seem affected. I start the skimmer and it goes away in few hours. My coral seem to even like the spores.
My temperature is 76F though, so I guess that surely help to keep a good level of oxygen in my tank. Bioload in 75 gallons: kole tang, niger trigger, copperband butterfly, clownfish, 3 pajama cardinal, green mandarin.
Maybe it was a combinaison of a few things?

Occam's Razor.
