How to Get Rid of Black Algae in Your Swimming Pool (and Keep it From Coming Back)

Hello, my friend, hello again; today we come together to talk about How to Get Rid of Black Algae in Your Swimming Pool (and Keep it From Coming Back) and hope the blog can help you.

After speaking to pool professionals, we’ve put together a guide that will beat the persistent nuisance of black algae growth once and for all.

Black algae in a pool is not just unsightly. Although it isn’t harmful itself, it can spread rapidly and harbor dangerous bacteria, like E. coli, that can make swimmers sick. And if it gets into the pump and filtration system, it can damage equipment. Once established, it becomes a persistent problem and even when you think you’ve cleaned the pool properly, black algae can quickly reappear.

We consulted with installers and professional pool cleaning experts to learn how to get rid of black algae in a pool and how to prevent it from coming back.

What is Black Algae and Where Does it Come From?

Algae are mostly aquatic organisms that vary in size from microscopic to enormous. Kelp, which can grow to 200 feet long, is actually an algae. Many algae species are useful and ecologically beneficial—some are a valuable food source for freshwater and saltwater creatures and others are used as a biofuel.

Problems start to occur when certain types of algae grow rapidly and form mass blooms in our waterways. It can also happen in swimming pools, where they are one of the common reasons why the pool water goes green.

Black algae’s natural habitat is streams, rivers and lakes. Cross-contamination brings it into pools. Although black algae itself is not dangerous, it’s not a good idea to swim in an infected pool because of the risk that other more harmful bacteria are living in it.

How to Treat Black Algae in a Pool

Let’s look at two approaches to black algae removal based on how severe the problem is. The first is relatively easy, and it might work if you catch it early enough. The second is a proven process for combatting more serious infestations.
