I don't have pictures, but I put towels over the front and one side of my tank (held up with soup cans on top of the canopy) for an almost total blackout for a day. My wife couldn't handle the fish "being scared" anymore the next day, so I took down the towel and left the light off for two days.
That seemed to clear up much of the problem. Since then, I've been limiting the lights to 6 - 8 hours a day. What I thought was cyanobacteria (but am now thinking may have been dinoflagellates) seems to be gone.
As an aside, the morning after the day the tank was covered with towels, I found our blenny dried up on the floor behind the tank. Jumping was some feat since it had a mere 1.5 inches of clearance between the glass top and the edge of the tank. We'd had it for a few weeks without incident, so I wonder if the near total darkness for a day caused it to "panic" or otherwise behave erratically?
that's good news. make sure you do a water change just after to rid the tank of all the dead junk/funk!
. i don't know if you're keeping a reef or not but If you don't have corals i would use very little light intensity and for short hours. this will make your tank stay clean much longer and have less maintenance but the trade off is little or no coralline .
