One of the most challenging nuisances pool owners face is black algae in their pools. These dark, stubborn organisms can cause trouble for pool caretakers and be difficult to eliminate without proper treatment.
Understanding what causes black algae in pools and how to address it effectively is key to keeping your pool pristine. So, to help you with your pool problems, we will explore ways to prevent and eliminate black algae, as well as provide answers to frequently asked questions.
What Is Black Algae?
Black algae are a type of algae that appear as dark, bluish-black spots on the pool surface. Unlike the more common green algae, black algae spots in swimming pools tend to form in cracks and crevices, particularly in the grout lines of pool tiles, on pool walls, and in corners.
While black algae in pools is not necessarily dangerous to humans in terms of immediate health risks, it can impact the appearance of your pool. Plus, black algae can also indicate that your pool's water chemistry is off-balance, which may lead to other issues if left unchecked.
What Causes Black Algae In Pools?
Black algae can indicate a problem in your pool's water chemistry, sanitization, or even the pool equipment! Several factors contribute to the growth of black algae. Understanding these causes is the first step in prevention. Here are the main reasons behind these black spots:
- poor sanitization;
- imbalanced water chemistry;
- stagnant water; and
- contaminated pool equipment.
As the hotter months roll in, you will probably want to reopen your pool for Spring so you and your kids to enjoy refreshing baths. So make sure to check everything before pool season starts so that everybody is safe and healthy!
How To Get Rid Of Black Algae In Your Pool?
Cleaning the pool completely and using the right chemicals, like chlorine or even algaecide are the best ways of getting rid of black algae in the pool. It can be a multi-step process, but with patience and the right tools, it is possible.
Follow this guide on how to eliminate black algae in the pool and go swimming in no time!
1. Brush The Pool Thoroughly
Start by scrubbing the affected areas with a stiff-bristled pool brush to break apart the algae. Focus on tiles, walls, and pool steps where black algae may hide.
2. Shocking The Pool
Shocking the pool with a large dose of chlorine is one of the most effective ways to kill the algae. This strategy goes for saltwater pools as well. Use a high-quality pool shock product, and follow the manufacturer's instructions for the correct dosage. Be sure to apply the shock in the evening to avoid the chlorine being too quickly broken down by sunlight.
3. Use Algaecide
Specialized algaecides formulated for black algae in pool removal can also be very effective. Look for a product that contains copper sulfate or quaternary ammonium, as these are known to kill black algae spores. Apply the algaecide according to the instructions, and make sure the water remains circulating for the best results.
4. Check And Adjust Water Chemistry
After treating the algae, check the pool's water chemistry, including the pH, alkalinity, and chlorine levels. Maintaining balanced water will help prevent the growth of future algae outbreaks.
5. Run The Pool Filter
To guarantee that all dead algae and debris are removed from the pool, run your filter continuously for 24-48 hours after treatment. Be sure to clean or backwash your filter regularly during this time, and check the filter pressure to ensure optimal performance and cleanliness. Also, always keep your pool plumbing repairs up to date.
6. Repeat The Treatment If Necessary
In cases of severe black algae infestation, you may need to repeat the treatment. Some pool owners may find it necessary to apply a second dose of algaecide or chlorine shock to completely eradicate the problem.
4 Tips To Prevent Black Algae From Returning
Preventing an outbreak is key; ensure your pool is clean, sanitized, and well-circulated. Covering the pool helps prevent algae growth. Here are a few extra tips to keep black algae from returning:
- Keep your pool water balanced by regularly testing and adjusting the chemical levels, especially the chlorine.
- Clean your pool frequently and thoroughly to remove any organic material that can feed algae growth. It includes brushing the walls and steps and vacuuming the pool floor.
- Confirm that your pool's filtration and circulation systems are working properly.
- If your pool is not in use for an extended period, consider covering it to prevent debris and algae spores from settling in.
By following the steps outlined above, you can effectively kill black algae in your pool and prevent future growth. With the right approach, materials, and chemicals, you will be able to restore the beauty and cleanliness of your swimming area in no time!
