Bleaching the tank works well.  You fill it up, add a cup or two of bleach,
put on a tight fitting glass cover, and wait a day or two.  the fumes of
the bleach will even bleach things above the water level in a few days.
Then drain , rinse well, and it is ready to go.  Very likely, however, you
will reintroduce cyanobacteria with the fish and plants, and so don't
expect to have gotten rid of it forever like you can do with hair algae.
