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.

Easy...

1. Increase flow to the problem areas.

2. Remove nutrients via Phosphate sponge and other various water

3. purification products like Chemi-Pure

4. Siphon some out if you can (comes off nice via, turkey baster...slurp)

5. Just to get a head start on it...and don't use it more than once...Mardel
Sal****er Maracyn
It kills back bacteria...ALL BACTERIA.

Some people will say stay away, use it.

6. Cut back a bit on the lighting...8 hours.

7. Oh yeah, patience...we all deal with cyano.
You never kill it, you just control it.
