I have MH and UV/RB LED.

I still have them.

For a period of about a month, the glass on the double ended MH bulb was off (not intentionally). This was before there were any corals in the tank - and the rocks at the very top were completely bleached dead due to the UV radiation. It was like a complete elimination of all life... not even algae could grow there.

That may have been one of the causes of the dino flareup... lack of life... I'm sure the surface water plankton was decimated by day.
