Leaving the lights off for a couple of days definitely has improved the
problem, but it's still there. I'll read up on cyanobacteria, and how
to get rid of it.

Cyanobacteria is a little more tricky than hair algae.

Hair algae likes high nitrates, and cyanobacteria does not
like high nitrates, and it likes to take free nitrogen,
and fix it into nitrates. Cyanobacteria can wiggle like a
worm. I've got some vidio on my camcorder of cyano under
the microscope wiggling like worms.
