I can't be positive but this sounds like a breeding event. These guys are broadcast spawners and so they release a lot of gametes (eggs/sperm) into the water at once.

Normally anything that isn't...

The added stress isn't very significant, and doesn't surpass what a coral might face in the wild. Remember that if you are using 10 - 20k bulbs, you are already showering your corals in some UV-A...

I think you're misunderstanding mine and Dr. Joshi's argument. He is saying that it is a myth that DE bulbs are always brighter than SE bulbs, whereas I am saying that it is still a good general rule...

I don't think it would. UV light taxes zooxanthellae by requiring them to produce these defensive pigments. This requires energy and nutrients and so would compete with growth and reproduction.

For the same brand of bulb, HQI does put out more light per watt, and conversely generates less heat per watt. I've been told that this is a feature of bulb design, and has to do with the fact that...
