So presumably this just ups the circulation at night? Are there any issues
about leaving a powerhead on a timer? What do you do with the intake (I
have no undergravel filter)

Is there anything
else I could try that wouldn't cause splashing at the surface, but would
get
more o2 into the water overnight?

I use a powerhead. It's adjustable, and I set it so that it's underwater,
aimed just slightly toward the surface. It doesn't splash, and the fish
are
much happier.
