What Kills Mustard Algae In A Swimming Pool?
More commonly known as yellow algae, mustard algae, is a problem many pool owners may face, especially in the southern region of the U.S. Mustard algae looks like yellow or brown spots that are often found on pool floors, walls, and even equipment. Learn how to kill algae growth in your swimming pool below.
What Is Mustard Algae In A Pool?
Before you know how to kill mustard algae growth, you must understand exactly what it is. This is a chlorine-resistant form of algae, thriving in warm, sunny climates.
Oftentimes, mustard algae looks similar to pollen, sand, or dirt. However, if you try to simply brush it off, you’ll notice how stubborn it can be. When left untreated, the algae can spread quickly and become a persistent issue.
How To Tell If There Is Mustard Algae In Your Pool
Typically, mustard algae will be found in the following places:
- Warm, humid locations.
- Places where wildlife may enter the pool or pool area.
- Pools located near forests or swampy areas.
Where are you likely to find mustard algae in a pool, though? Here are the most likely spots for its growth:
- Floors and walls of the pool.
- Shady areas of the pool.
- On pool equipment and/or toys.
- Areas featuring poor circulation.
How To Kill Mustard Algae
Even if you do everything you possibly can to prevent algae growth, it can still find its way into your pool. It’s important to act quickly in order to stop further growth once you spot these algae.
Step 1. Brush And Vacuum
- Brush any surfaces where mustard algae is present thoroughly.
- Use your pool vacuum after the brushing is complete.
- Set the filtration valve to waste in order to remove all algae.
Step 2. Hyperchlorinate The Pool
- To kill the algae, use a pool shock treatment.
- You may need to use a higher dose than normal to kill the stubborn mustard algae.
- Always follow the instructions on the shock treatment product for the best results possible.
Step 3. Use Algaecide
- Once the pool has been shocked, apply a mustard algaecide.
- This is used to kill any potential spores left over.
- Again, always follow the manufacturer’s instructions when using the algaecide.
Step 4. Thoroughly Clean Pool Equipment
- Remove everything that may have been in the water, including equipment, toys, and other accessories.
- Soak these in a solution containing water and chlorine.
- This mix can kill any remaining algae spores.
Step 5. Constantly Inspect The Pool Area
- As a last step in the process, it’s best to keep on eye on your pool’s water chemistry.
- Make any needed chemistry adjustments, at this time.
- Test the water each and every day to ensure all algae is gone.
Conclusion
Controlling and preventing the growth of algae will require regular pool maintenance. Once you have followed the step-by-step guide above to kill the algae, use these tips to prevent any future growth:
- Always try to maintain a free available chlorine residual of 4 p.p.m. at all times.
- Keep a regular cleaning and maintenance schedule for your pool.
- Make sure the pool pump and filter functions properly, always providing the proper circulation.
