A pool owner’s biggest nightmare is seeing algae growing in their swimming pool. Even running an automatic pool cleaner like a kreepy krauly won’t remove algae, especially if it has been left to grow for a long time.

This is because it sticks to the edges of the pool and protects itself from harm by a slimy covering or a very hard one.

There are many types of algae, of which 4 main types are likely to be found in swimming pools.

1. Green algae
2. Black algae
3. Pink algae and
4. Yellow algae

While algae is not harmful to humans of itself, it can become a host to bacteria such as e.coli that are. Besides that, it looks horribly ugly and will spoil all the pleasure you have in your pool and swimming in it.  If you have an algae infection in your pool it may not even be your fault. Algae spores can be blown into the pool where they wait for the right condition to grow and bloom.

Nearly all water sources have some kind of algae in them, including the ocean which is where black algae comes from.  Green algae is found naturally in many watery homes such as the local creek or river, or any pool of water.
