With over 7000 species growing in multiple habitats, green algae is very diverse – probably the most diverse.
This group of algae is paraphyletic as it excludes Plantae species which includes, mosses, plants, flowering plants and ferns. Green algae has two chlorophyll forms – just like plants – which captures light energy to facilitate the production of sugars.
Like the name suggests, green algae is green in color and slimy on the floors and the walls of pools. They usually grow on the ‘dead spots’ areas of the pool, which mostly happens during sunrise.
These are the areas where there is poor circulation and can’t be reached by an average brush when cleaning. And if it’s in a vinyl or fiberglass pool, these spots are very dangerous as they are very slippery, which means that chances of slipping and falling are very high.
But through super chlorination and brushing, the algae can be removed. If left unattended, green algae can easily take over your pool in one night. Remember you are fighting against Mother Nature here.
It’s my belief that working on pool problems is equal to being vegetarian; in that, the patient can’t inform you of the problem, meaning that you will have to treat all the symptoms in an aggressive manner.
And that only time can help you perfect in handling the problems. When it comes to the new pools, algae prevention should be a priority. There are some cases where shocking the pool makes the metals cling on the pool walls, which causes staining.
Older pools can, however, withstand a lot more than new pools can; always remember that.
