What is pool algae?

First up, let’s take a look at just what pool algae is. According to the dictionary, it is small, plant organisms that occur in fresh or salt water, made up of one or more cells. While they have chlorophyll, which colours them, they don’t have most of the other components that you’d think of when you think of plants, like roots, leaves, etc. There are many different types of algae, with some of the most common being classified by colour: green algae, brown algae, golden algae, yellow-green algae, etc. The most moon type of algae that forms in swimming pools is green algae, which can vary in colour from green, to blue-green, yellowy, etc. Your pool can also get black algae (in the cracks) and mustard algae, which can look like dirt.

How do you get pool algae?

Pool algae forms when you don’t properly chlorinate your pool. Algae can get into your pool from spores that exist literally everywhere outside that end up making their way into your pool. In the wet environment, and aided by light and heat, these tiny organisms can grow and multiply, leading to algal bloom in your pool. There is no way to keep these algal spores from making their way into your pool, the only thing you can do to ensure you never get algal bloom is to kill the spores once they get into your pool – which you do by keeping your pool chlorinated.

How do you kill pool algae?

Depending on the deepness of the colour of your pool (i.e. the degree to which the algae has taken over!) will indicate how you need to treat your pool. Once you have identified that you have an algal bloom, it’s time to then shock your pool. This means giving your pool a massive dose of chlorine to kill off that nasty algae. The darker the pool, the more chlorine that you will need. It is best to take picture in good lighting and them take them along to your local pool shop to get there advice on how much chlorine is necessary. The other option is to get in a pool professional to do it for you, which is the easier route!

How do you keep pool algae from coming back?

After shocking your pool, you’ll need to monitor chlorine levels until it returns to the normal suggested level. The only way to keep pool algae from coming back is to monitor your chlorine levels on a regular basis and always ensure that you are topping up when you need to. You want to be able to swim in your pool whenever you want, so make sure to keep the algae at bay with your pool chlorination!
