Different types of algae in swimming pools can be an indicator that the chlorine level is not sufficient. Algae can create foul odors and cloudy, discolored pool water.
A common type of algae found in swimming pools is black algae. Black algae are the hardest pool algae to treat and get rid of.
If black algae are observed to bloom in your above-ground pool, it is best to treat them before they spread. In this article, we’ll see what they are and give you black algae treatment tips.
What Is Black Algae?
Black algae are the most stubborn type of algae. It has a blue-green appearance and grows in crevices and angles of pools, typically in concrete, granite, and plaster pools.
However, they are not commonly found in pools made with vinyl liner and fiberglass. But this is not impossible. Black algae are more likely to be found in pools that have shady areas or during seasons that don’t have a lot of sunlight.
What Causes Black Algae in Pools?
A common cause of algae growth is insufficient chlorine levels in a swimming pool. The algae growth can also be caused by spores being transferred by wind or rain and live vectors, such as an impure bathing suit. A pool filter that is not running enough or not working properly can contribute to algae growth.
How to Get Rid of Black Algae in My Pool
The McGrayel Algatec 10064 is considered one of the best algaecides for black algae on the market, and we recommend it.
Its application should be done after the pool pump has been turned off so the area to be treated will sit undisturbed.
After the chlorine or algaecide has been added into the pool overnight, you can remove the algae with the brush.
You can also shock the pool with chlorine, which involves large doses of chlorine. You can also use an algae treatment product, such as one containing copper.
Copper is a natural algaecide that is an ingredient in many algaecides and is non-toxic. Swimming should be avoided when treating algae.
Prevention Is Key
If you’ve experienced algae infestation at least once in your pool, you have to be on high alert and maintain consciousness. Get a special algaecide for black algae and have it handy.
Applying an algaecide regularly, even when there is no algae growth, can help prevent future algae. After adding the algaecide, don’t use it for a few days after applying.
In addition, periodic maintenance, such as monitoring chlorine levels from testing pool water, adjusting suction, making sure filters are working properly, and all chlorine shock treatments, can prevent black algae growth.
