There is no such thing as actual black algae. It is just a name given to crystallized green algae. Green algae that can not flourish will die and crystallize and try to grow again and again in the same spot forming those black buds. Usually you will get black algae from keeping a constant level of chlorine say 3 to 5 ppm's and not shocking (Raising the chlorine level over 10 ppm's) the pool often enough.

When treating Black algae, it is important to note that the algae will grow "roots" into the pool's surface and therefore, the areas where the algae is growing needs to be vigorously brushed and retreated until it is removed. High chlorine levels, such as noted above, must be maintained for several days for best results.
Also keep in mind that Black algae will "use" any bio-films growing on pool surfaces. Especially concrete or plaster finish pools. Vinyl liner pools rarely have true black algae blooms. Bio-film removal leads to very successful Black algae treatment and even cure. Black algae, along with the bio-film, is very resistant to chlorine or bromine leading to mere bleaching of the algae rather than killing it.

It likes to grow in damp places like between bathroom tiles for example or badly drained roof guttering. It is also possible to introduce it into a pool by wearing the swimwear that was worn at the beach.
