How to Treat Mustard Algae in Your Above-Ground Pool

Mustard algae is a common challenge for pool owners, especially in above-ground pools. This stubborn, yellow-green algae clings to pool surfaces and can be difficult to eradicate. But with the right approach, you can keep your pool crystal clear and ready for fun. Here’s a step-by-step guide on how to treat mustard algae in your above-ground pool, brought to you by Hot Spring Spas & Pool Tables 2.

Step 1: Brush the Pool Thoroughly

Mustard algae sticks stubbornly to pool surfaces, so the first step is to break that bond. Use a stiff-bristle pool brush to scrub the walls, floor, and any other surfaces where the algae are present. Brushing not only helps remove the algae but also makes it easier for the chemicals to work effectively.

Step 2: Vacuum the Pool

Once you’ve loosened the algae, it’s time to get rid of it. Vacuum the pool thoroughly, paying special attention to the areas you just brushed. If your pool setup allows, vacuum to waste to prevent the algae from going through your filter and potentially causing more problems.

Step 3: Balance the Water Chemistry

To maximize the effectiveness of the treatment, make sure your pool water is balanced. Test and adjust the pH and alkalinity levels. The ideal pH range is 7.4-7.6, and your alkalinity should be between 80-120 ppm. Balanced water not only supports the treatment process but also helps prevent algae from returning.

Step 4: Shock the Pool

Mustard algae requires a powerful shock treatment to eliminate it completely. Use a chlorine-based shock product, and aim for a high dose of 30 ppm of free chlorine. For best results, dissolve the shock in a bucket of water before adding it to the pool, especially if you’re using granular shock. This prevents bleaching of your pool liner and ensures even distribution. Be prepared to repeat the shock treatment if the algae persist.

Step 5: Add Mustard Algaecide

After shocking the pool, wait for the chlorine level to drop below 5 ppm before adding a specialized mustard algaecide. This product is designed to target and kill mustard algae effectively. Follow the manufacturer’s instructions closely to ensure you’re using the correct dosage.

Step 6: Run the Pool Filter Continuously

Now that the chemicals are in the water, it’s time to circulate them. Run your pool filter continuously for at least 24-48 hours after treatment. This helps to evenly distribute the algaecide and shock while filtering out the dead algae.

Step 7: Clean or Backwash the Filter

Mustard algae can clog your pool filter quickly, so it’s crucial to clean or backwash the filter after treatment. For sand or DE filters, perform a backwash. For cartridge filters, clean them thoroughly to ensure they are free from debris and algae.

Step 8: Test the Water Again

After completing the treatment process, test your pool water again. Make sure the pH, alkalinity, and chlorine levels are within the ideal range. Adjust as necessary to keep your pool balanced and safe for swimming.

Step 9: Prevent Future Outbreaks

Prevention is key to keeping mustard algae at bay. Regularly clean your pool, maintain proper chemical levels, and consider using a preventive algaecide as part of your routine maintenance.
