What do you if have clusters of black dots on the surface and bottom your swimming pool?

If you have clusters of black dots on the surface and bottom of your swimming pool, it's important to address the issue promptly to maintain a clean and healthy swimming environment. Here's what you can do:

1. Identify the Cause:

- Determine whether the black dots are dirt, algae, or a buildup of debris.

2. Clean the Pool Surface:

- Use a pool brush or vacuum to thoroughly remove the black dots from the pool surface and walls.

3. Shock Treatment:

- Add a shock treatment (chlorine or non-chlorine) to kill bacteria and algae in the pool. Follow the manufacturer's instructions for your pool's size.

4. Check Chlorine or pH Levels:

- Test the pool's chlorine and pH levels to ensure they are within the recommended range. Adjust accordingly.

5. Filter Cleaning:

- Clean the pool filter to ensure it's removing dirt and debris effectively.

6. Circulation:

- Ensure proper circulation of pool water by running the pump for the recommended duration each day.

7. Vacuuming:

- Regularly vacuum the pool, especially the areas where black dots appear, to remove settled debris.

8. Use Algae Prevention Products:

- Add a phosphate remover to the pool water. Phosphates contribute to algae growth, so removing them can help prevent the recurrence of black dots.

9. Inspect and Repair:

- Inspect the pool liner or coating for any cracks or damage that may be contributing to the accumulation of dirt or algae. Repair any cracks or damage as necessary.

10. Maintain Regular Maintenance:

- Establish a regular maintenance routine to prevent the buildup of dirt and algae in the future.

Remember, the specific approach may vary depending on the nature of the black dots and your pool setup. It's a good idea to consult a pool maintenance expert or refer to your pool's owner's manual for specific recommendations.
