When was the last time you took a close look at your Phoenix pool? If you haven’t been mindful of what’s going on beneath the water as of late, you might be taking a dip in a pool that contains black algae and not even realize it!

Black algae is problematic for pool owners and aquarium enthusiasts alike. Aquatic Community stated that it primarily forms on the surfaces of moist items such as the walls of a pool. It can begin to show itself in the form of little black dots until it starts to bloom. Once it begins to thrive, black algae grows multiple layers for protection. Treating the top layer of the algae and failing to eliminate the entire growth can result in lingering problems.

Even if you have a properly working salt system and maintain your pool adequately throughout the year, you’re at risk of black algae, which can be stubborn and tough to remove. However, you don’t have to let this plant matter take over your pool. There are a few ways you can begin to tackle the problem and ensure that it doesn’t happen to you again in the future.

1. Begin scrubbing with a durable brush
If you’ve only noticed a small patch of black algae growing along the side of one of your pool walls, you might be able to stop it in its tracks by giving it a good scrubbing. Remember that you need to be able to remove more than just the outer layer of the algae to keep the plant matter from returning.

2. Check the filtration
Aquatic Communities stated that you want to make sure that your filtration system is working properly. A problem with your system could be contributing to the development of black algae in your pool, and it may also allow other debris to linger.

3. Remove dirt from the pool
In addition to checking the filtration system, it’s a good idea to remove all of the dirt with a vacuum that can make its way to the bottom of your pool, as this may be contributing to the black algae problem. As you do so, be sure to monitor the pH level of the pool and adjust it as necessary.

If you’re finding trouble tackling the problem, don’t hesitate to contact a Phoenix pool maintenance professional to take care of the black algae in your pool!
