If it is genuine 'black algae' it is very difficult to remove without emptying the pool and gouging the black algae out of the pool surface. Other algae can be removed by shocking the pool, filtering continuously and brushing walls while maintaining a good sanitizer level.
Shock the pool add algaecide and scrub down the sides and bottom of the pool with a stiff pool broom there should be a lot of dead algae on the bottom of the pool the next day. vacuum it to waste if you want to avoid the risk of pushing life algae through the filter and back into the pool.
Black Algae presents in 1 to 3cm black (or dark blue green) spots, It forms in a layers. the first layer may be killed by chlorine but protects further layers from destruction. This form of algae is slow growing and hardy. It is extremely chlorine resistant. to treat Black algae. Turn of the pump,Brush the algae spots thoroughly with a hard brush. then use chlorine tablets to treat the algae spots individually (this is not recommended for vinyl pools). Pour a concentrated all purpose algaecide on the algae spots. Leave it overnight. Restore water circulation, brush dead algae and vacuum it to waste. You may have to repeat the process .when you are finished, check the water balance shock the pool and make sure that you keep the chlorine up to it to help prevent further out breaks.
---- Green Algae: A very common variety, It is often found floating free in the water, and also clings to the pools walls. Unlike severe copper precipitation green algae reduces water clarity, Green algae's also appear as "spots" on surfaces, in rough places, or areas where circulation is low.Yellow Algae: This variety of algae clings to walls and is also referred to as mustard algae. It is generally found on the shady side of the pool, is sheet forming, and difficult to eradicate completely. This variety is resistant to normal chlorine levels and requires extra effort to eradicate.Black Algae: the hardest algae to get rid of, Black algae has a root system and a protective waxy coating that makes eradication extremely difficult. Black algae appears as dark black or blue/green spots, about 3 or four millimetres across, They have roots that can extend into the plaster or tile grout, ----
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.
because the rocks preduce the right situantions for them to live
Yes, a pool can get orange algae.
Black algae shows itself as small black spots on the pools floor walls and fittings untreated they grow. Green Algae often starts as a greenish tinge on the walls or other surfaces of the pool and spreads into the water making it turn green if left untreated.

By killing the green algae with an algaecide available at your pool shop.
The sand filter wont make a pool green this happens a s a result of algae.
When a pool turns green, the cause is the build up of algae. To remove the algae, chemicals will need to be bought to restore the PH levels in the pool, killing the algae.

If there are just a few spots and you do not wish to drain the pool you must first scrape the "head" off with a wire brush or algae stone and then apply a granular/powder chlorine directly on top of the spot. If the pool is riddled with the stuff it would probably be easier to drain the pool, scrape off the heads of the black algae and then chlorine wash the pool. Let the chlorine sit for a half hour before rinsing.
