Though yellow or mustard algae does not spread as fast as the green one, destroying it is harder compared to green algae.

Cleaning will definitely be harder, but it will bring back the natural beauty and hygiene in your pool. You can get rid of yellow or mustard algae following some simple steps.

Black Algae

Perhaps the nastiest and the most aggravating relative of the green algae. It is extremely hard to eradicate completely for its strong root concentrated on the surface of your pool. The roots even penetrate the tile. Looks like dark black or blue/green spots and size varies from small to medium. 

Besides, the protective layer over their heads protects them from chlorine or shock. Meaning that it can grow even in the high presence of any chemical. Unless you destroy the evil roots, they will come back even after you drained all the water out. 

Pink Algae

Also known as pink slime or pink mold, the Pink algae are the rarest type among its family. Not algae, rather one kind of bacteria, you will find in PVC pipes and sometimes, in your pool. Having a smiley appearance, you will often confuse it with green algae.

Though you can swim through it as it is not harmful to humans, it looks unhygienic. It requires high-level chlorine shock, like black algae, to be completely removed.
