I have to really wonder about the low O2 theory - the atmosphere is
20,000 ppm oxygen, and raindrops are pretty small, even at their
largest. I think there is plenty of time for oxygen to diffuse into
the drop as it nears the ground.

Of course, those of you with rain and an O2 meter could solve the
question pretty easily.

I would tend to think the deaths would be due to a rapid change in
water chemistry like pH or hardness, or possibly temp.

If the algae is dying, I think I would look at pH changes.
